Methoxyphenyl Substituted Bis(picolyl)phosphines and Phosphine Oxides
European Journal of Inorganic Chemistry, 2016AbstractThree new derivatives of methoxyphenyl‐substituted bis(picolyl)phosphines 3–5, the CH2TMS substituted bis(picolyl)phosphine (6) and related phosphine oxides 2b–5b have been synthesized. Syntheses were accomplished by reacting the corresponding dichlorophosphines with picolylTMS (7).

P-Arylation: Arynes to Aryl-Phosphonates, -Phosphinates, and -Phosphine Oxides
Organic Letters, 2013Synthesis of organo-phosphorus compounds and their application in organic synthesis and life sciences has been a topic of contemporary interest. Michaelis-Arbuzov reaction is the most extensively utilized method for their preparation, which works well only with aliphatic halides.

Highly Chemoselective Metal-Free Reduction of Phosphine Oxides to Phosphines
Journal of the American Chemical Society, 2012Unprecedented chemoselective reductions of phosphine oxides to phosphines proceed smoothly in the presence of catalytic amounts of specific Brønsted acids. By utilizing inexpensive silanes, e.g., PMHS or (EtO)(2)MeSiH, other reducible functional groups such as ketones, aldehydes, olefins, nitriles, and esters are well-tolerated under optimized ...

Diethyl-(?-dialkylcarbamoylethyl)-phosphine oxides
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19671. Diethyl-(β-chloroformylethyl)-phosphine oxide has been obtained by the reaction of diethylchlorophosphine with acrylic acid. 2. When the product of the interaction of diethylchlorophosphine and acrylic acid (without purification) is treated with secondary amines, diethyl-(β-dialkylcarbamoylethyl)-phosphines are obtained.

Preparation of functionalized phosphine oxides and phosphine sulfides
2014(±)-tert-Butylphenylphosphinothioic acid was resolved into (Rp)-(+) tert-butylphenylphosphinothioic acids 129 according to a standard procedure. The (±)- and (Rp)-phosphinothioic acids were converted into (±)- and (Rp)-tert-butylphenylthionophosphinochloridates 139 respectively by treatment with either thionyl chloride or oxalyl chloride in ...
