Novel hexacoordinated phosphate anions consisting of a central phosphorus(v) atom and at least one tetrachloropyrocatechol ligand can be simply prepared in modest to decent yields (37-71%) as their dimethylammonium salts following a one-pot process and with simple, usually commercially available, starting materials. A variety of symmetrical diones (alpha-diketones or ortho-quinones) can be used in this protocol and the structurally-diverse products are chemically stable when two tetrachloropyrocatechol ligands surround the P atom.

(Chemical Equation Presented) Buried in the symmetry: Phosphorylation of ortho-substituted binol derivatives leads to monodentate phosphites (X = OR) or phosphoramidites (X = NR2) having stereogenic centers at phosphorus (see scheme). Such compounds are excellent ligands in rhodium-catalyzed olefin-hydrogenation (95-99% ee) surpassing the C2-symmetric parent ligands.

Two novel chiral thiophosphoramides and two chiral phosphoramidites were synthesized starting from (S)-alpha-phenylethylamine and (R)-(+) or (S)-(-)-1,1′-Bi-2-naphthol (BINOL), respectively, and their application in combination with Lewis acid as cocatalysts in asymmetric Morita-Baylis-Hillman (MBH) reaction was investigated. Dramatic rate acceleration (the corresponding adducts were obtained in fair to excellent chemical yield within 15 min-5 h) was observed in these chiral phosphorus reagents/Lewis acid cocatalyzed MBH reaction between 4-nitrobenzaldehyde and activated alkenes, and in one case, moderate enantioselectivity was achieved (the corresponding adduct’s ee value is 44%).

Lawesson’s reagent 1 reacts with xanthen-9-ylidenemalono-nitrile 3 to give adducts 5a, 6a and 7, respectively. In case of the reaction of fluoren-9-ylidenemalononitrile 4 with 1, only 3-amino-2-fluoren-9-ylidene-3- thioxopropanenitrile 5b is obtained together with trimer 7. Whereas, trisdialkylaminophosphines 2a,b reacts with nitrile 3 to give the dipolar adducts 8 and 9, the corresponding dialkylaminophosphonate adducts 10a and 10b are obtained from the reaction of 2a,b with nitrile 4. Structural reasoning for the new adducts was based on compatible analytical and spectral data.

Several new alpha-alkoxy- and alpha-hydroxyphosphonate derivatives of tetrazole-quinolines were synthesized from the reaction of 2-azidoquinolines 3-carboxaldehyde 1a,b with trialkyl phosphites and dialkyl phosphites. On the other hand, azaphospholes 12a,b were obtained by treating 1a,b with tris(dimethylamino)phosphine. Furthermore, Perkin-type condensation of 1a,b and tetraethyl methylenebisphosphonate provided the corresponding tetrazoloquinoline-based bisphosphonate esters 14a,b. Based on the prediction results (PASS program), the anti-inflammatory activity of the prepared compounds was determined in vivo by the acute carrageenin-induced paw edema in rats. Many of the new compounds exhibit considerable anti-inflammatory properties at a dose of 50 mg/kg body weight. Especially 14a and 14b revealed remarkable activities compared with indomethacin, which was used as a reference standard in this study.

A versatile reactivity from the cage compound P(NMeNMe)3P is presented. The Staudinger reaction with Me3SiN3 is carried out. The crystal structure of the compound issued from the reaction on both sides (Me3SiN=P(NMeNMe)3P=NSiMe3) is reported. When the reaction occurs on only one side, the remaining free phosphorus atom is complexed with RuCl2(p-cymene). P(NMeNMe)3P reacts with PCl3, leading to the heterocyclic compound ClP(NMeNMe)2PCl. This heterocycle also displays a versatile reactivity. Substitution reaction with HNiPr2 leads to iPr2NP(NMeNMe)2PNiPr2. Very complex 1H and 13C NMR spectra suggest that the cis isomer is the largely major isomer of this compound. The cis structure is confirmed by X-ray diffraction. Besides the reaction on the P?Cl functions, the reaction on the lone pair of ClP(NMeNMe)2PCl is carried out, leading to the complex (p-cymene)Cl2RuPCl(NMeNMe)2ClPRuCl2(p-cymene). Characterization of this compound by X-ray diffraction displays a cis isomer for this compound also.

Deconstructing the tridentate (triphos)Pt(II) first-generation catalysts into mixed diphosphine/monophosphine combinations (P2P) has led to new, more active catalysts for the cycloisomerization of 1,6-, and 1,7-dienes into bicyclo-[3.1.0] and -[4.1.0] products. When the diphosphine was the small bite angle dppm, reaction rates were ?20-fold faster than with triphos, although reaction rates and diastereoselectivities were also sensitive to the monophosphine (PMe3 being optimal for rate, PPh3 being optimal for selectivity). When the diphosphine was xyl-BINAP or SEGPHOS, the catalysts were enantioselective, and enantio-ratios up to 98:2 were observed. Both sets of catalysts showed enhanced functional group tolerance in comparison to the original (triphos)Pt2+ catalyst. X-ray structures for both precatalysts are also reported.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 1608-26-0, you can also check out more blogs about1608-26-0
