Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry.

Organosilicon compounds, because of their unique properties, are widely used in a variety of organic processes, and thus the constant improvement of current methods is still needed. We present slurry-phase hydrosilylation reactions using novel supported ionic liquid-phase (SILP) catalysts containing rhodium complexes immobilized in four phosphonium ionic liquids (ILs) on silica support. The obtained new SILP catalysts were analyzed by IR technique, low-temperature nitrogen physisorption at 77 K, and scanning electronic microscopy with energy-dispersive X-ray spectroscopy to provide structural information on these materials. Moreover, the catalytic activity in hydrosilylation reactions was evaluated and compared with the catalytic activity of rhodium catalysts dissolved in the same ILs when using a biphasic reaction system (IL/catalyst as one phase and mixture of substrates as a second phase). The rhodium-based SILP catalysts proved to be much more efficient than when used in a biphasic system composed of a similar catalyst and reactants. Furthermore, as a result of the presented study, we have identified a highly active SILP catalyst ([{Rh(μ-OSiMe3)(cod)}2]/[P66614][NTf2] supported on silica) that allowed us to decrease the amount of catalyst used in the reaction by 1000 times in comparison with the amount of catalyst required while performing reaction using the biphasic catalytic system. The proposed method of utilization of SILP materials can become a significant step in reducing expensive organometallic catalyst consumption in organic chem. and, when applied more broadly, lead to significant cost savings, eventually making the production of many organic mols. more sustainable.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis, characterization and electronic properties of naphthalene bridged disilanes, published in 2019, which mentions a compound: 14694-95-2, Name is Tris(triphenylphosphine)chlororhodium, Molecular C54H45ClP3Rh, Synthetic Route of C54H45ClP3Rh.

Synthesis of naphthalene bridged disilanes 2R (R = Me, Ph) was performed via catalytic dehydrocoupling. Using RhCl(PPh3)3 as a catalyst, an intramol. Si-Si bond was readily formed from the corresponding disilyl precursors 1R (R = Me, Ph). For catalytic reactions using (C6F5)3B(OH2), bridged siloxanes (3Ph and 3Me) were observed Attempts to install the 1,8-naphthalene bridge directly onto a disilane resulted in an unusual product (4), containing two silicon centers bridged through one naphthyl group, and another naphthyl group attached to a single Si center. In order for this product to form, both a Si to Si hydrogen shift rearrangement as well as Si-Si bond cleavage occurred. The effects of Ph and Me substitutions on the structure and electronic properties of the synthesized compounds was investigated by single crystal X-ray diffraction, as well as IR and multinuclear NMR spectroscopic anal. In addition, theor. UV-Vis absorption maxima were evaluated using d. functional theory (TD-SCF) on a B3LYP/6-31(++)G** level of theory and compared with exptl. UV-Vis spectroscopic data.

The second generation of poly(propylene imine) dendrimer peripherally terminated by propionation (G2-P) was synthesized. The structure and composition of G2-P were characterized by Fourier transform IR (FTIR) spectrometer, 1H NMR spectroscopy (NMR), 13C NMR, matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS) and elemental anal. The encapsulated catalyst (G2-P(Rh3+)) was prepared by the coordination between G2-P and RhCl3·3H2O, and applied to the hydrogenation of nitrile-butadiene rubber (NBR) and styrene-butadiene rubber (SBR). G2-P(Rh3+) displayed excellent catalytic activity and selectivity for NBR and SBR hydrogenation, and Rh residue contents for hydrogenated NBR (HNBR) and hydrogenated SBR were only 80 ppm and 35 ppm resp. without any post treatment, which decreased 69.8% and 80.9% resp. compared with those of RhCl(PPh3)3.

RhCl(PPh3)3 catalyzed [4+2] intramol. cycloaddition of optically active axially chiral allene-dienes afforded cis-fused [3.4.0]-bicyclic products with three chiral centers in good yields with an excellent chemo- and diastereoselectivity.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Tris(triphenylphosphine)chlororhodium, is researched, Molecular C54H45ClP3Rh, CAS is 14694-95-2, about Synthesis of dicyano-substituted ε-caprolactone and its (co)polymers.Formula: C54H45ClP3Rh.

A synthetic approach to the dicyano-substituted ε-caprolactone was developed. It consists of a cyclohexanone ring assembly through the Diels-Alder reaction followed by the Baeyer-Villiger oxidation Ring-opening polymerization of the synthesized monomer, catalyzed by the aluminum alkoxides, was performed in a well-controlled manner and provided the nitrile-polyester homopolymers of various molar masses. The synthesized nitrilePCL homopolymers are amorphous with a significantly higher glass transition temperature (66-69 °C) compared to the unsubstituted PCL. The dicyano-substituted ε-caprolactone monomer was copolymerized with the unsubstituted ε-caprolactone to prepare the statistical and block copolymers. Furthermore, the cyano groups of the nitrilePCL homopolymers were transformed into the amide groups by post-polymerization modification under anhydrous conditions using the Wilkinson’s catalyst. The resulting amide-functionalized polyesters are water-soluble when the degree of transformation is higher than 80%.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Tris(triphenylphosphine)chlororhodium( cas:14694-95-2 ) is researched.Name: Tris(triphenylphosphine)chlororhodium.Chen, Dou; Mo, Gaoming; Qian, Junmin; He, Liu; Huang, Qing; Huang, Zhengren published the article 《Synthesis of cyano-polycarbosilane and investigation of its pyrolysis process》 about this compound( cas:14694-95-2 ) in Journal of the European Ceramic Society. Keywords: cyano polycarbosilane pyrolysis process. Let’s learn more about this compound (cas:14694-95-2).

Polycarbonsilane (PCS) is an important precursor of silicon carbide (SiC) fibers and ceramics. The ceramic yield of PCS is relatively low, about 60 %, which may bring some deficiencies in its applications. In this work, a novel precursor cyano-polycarbosilane (PCSCN) is synthesized by hydrosilylation reaction between PCS and acrylonitrile using a rhodium-containing catalyst, although acrylonitrile is generally not easy for hydrosilylation. After introducing tiny amounts of cyano (-CN) groups into the PCS mols., the ceramic yield of PCSCN can increase largely to over 80 %. The ceramization mechanism of PCSCN is investigated by FTIR, TG, XPS, ESR, NMR, Raman and XRD analyses. It is found that some crosslinking structures in PCSCN are formed between Si-H bonds and -C[n.58118]N groups from about 200 °C, which can be responsible for the high ceramic yield. The existence of a little more N, O and free C elements in the pyrolysis products may inhibit the growth of crystalline β-SiC. Moreover, the PCSCN precursor can also be melt-spun into continuous fibers by tailoring its mol. weight and softening point. The oxidized PCSCN fiber with relatively low oxygen content can be pyrolyzed without melting, and the final SiC fiber with an oxygen content as low as 8.5 % is obtained.
