Application of 13406-29-6, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.13406-29-6, Name is Tris(4-(trifluoromethyl)phenyl)phosphine, molecular formula is C21H12F9P. In a patent, introducing its new discovery.

We report here on the syntheses of rhodium(I) complexes bearing a phosphine-quinolinolate ligand and the isolation of two classes of important intermediates in the anti-Markovnikov hydroamination of terminal alkynes with secondary amines: vinylidene-bridged dirhodium complexes and (amino)carbene complexes. We first prepared various rhodium(I) complexes bearing a phosphine-quinolinolate ligand and found that some of these complexes had catalytic activity for the anti-Markovnikov hydroamination of terminal alkynes with secondary amines. The reaction of stoichiometric amounts of a (PNO)Rh complex with terminal alkynes provided vinylidene-bridged dirhodium complexes. When the resulting vinylidene complexes were reacted with secondary amines, (amino)carbene complexes were generated, which gave the hydroamination product upon heating with an additive. These results suggest that this anti-Markovnikov hydroamination catalyzed by (PNO)Rh complexes proceeds via vinylidene and (amino)carbene complexes.

Diastereoselective syntheses of the unusual dimers, 4-heptyl-2-(2?- hydroxy-binaphthyl)hydrogen phosphonate (5) and the cyclohexyl analogue (7), are achieved by hydrolysis of 4-(3,5-dioxa-4-phosphacyclohepta[2,1-alpha;3,4- alpha?]dinaphthalene-4-yloxy)heptane (4) and the cyclohexane analogue (6), respectively. Two out of eight possible pairs of monomers units are involved in the stereoselective formation of the dimer 5a of configuration BINOLR-PS:BINOLR-PS: this is determined by X-ray crystallographic data, which reveal a centrosymmetric, 18-membered ring structure with Ci symmetry, consisting of two monomers strongly hydrogen-bonded between the oxygen of P=O units and hydroxyl hydrogen atoms. Mass spectrometric, melting point, and thermal decomposition point data, as well as NMR data, support the presence of strong, quasi-covalent hydrogen bonds. Computational analysis suggests that the diastereoselectivity is controlled by molecularly constrained geometry of the monomer. Compound 7, although not characterized crystallographically, appears to be analogous to 5.

A common strategy to synthesize 4/6-(4-(4-methylpiperazin-1-yl)-6-(4-(4- oxo-2-phenylthiazolidin-3-yl)phenyl)-1,3,5-triazin-2-yloxy)benzonitriles/ nicotinonitriles was developed by applying an efficient palladium-catalyzed C-C Suzuki coupling. Moreover, the synthesized compounds were also tested for their in vitro antimycobacterial activity against Mycobacterium tuberculosis H 37Rv using BACTEC MGIT and Lowenstein-Jensen MIC methods. Several compounds displayed profound antimycobacterial activity in combination with low toxicity towards mammalian cells. The best results were observed amongst the nicotinonitrile substituted s-triazine analogs and it could be a potential starting point to develop new lead compounds in the fight against M. tuberculosis H37Rv. The newly synthesized compounds were characterized by IR, 1H NMR, 13C NMR, MS and elemental analysis.
