Silylphosphanes 3 and 4 gave 1,4-additions with the O=C-C=C moiety of oxazolones 1a-e and 2a-f to afford the adducts 5–8. Oxidation or sulfuration of 5–8 followed by hydrolysis led to oxyphosphorus (or thiophosphorus) amido-acids 9–11 and 15, 19, 20 respectively. A great difference was observed in the behaviour of thiophosphane oxides 16 (R = Me) and 17(R = Ph) toward hydrolysis: 16 led directly to

A review of the methods available for the preparation of monodentate P(III) compounds containing fluoroalkenyl, fluoroalkynyl and fluoroalkyl groups is given. The synthesis, properties and coordinationchemistry of some fluoroalkenyl- and fluoroalkynyl-containing phosphines derived from HFC-134a (CF3CH2F) and HFC-245fa (CF3CH2CH2F) is summarised. The development of the reaction between trimethylsilyl-containing
综述了可用于制备含有氟烯基,氟炔基和氟烷基的单齿P(III)化合物的方法。总结了一些衍生自HFC-134a(CF 3 CH 2 F)和HFC-245fa(CF 3 CH 2 CH 2 F)的含氟烯基和氟炔基的膦的合成,性质和配位化学。含三甲基甲硅烷基的膦与R f I之间反应的发展,这提供了一种通用的方法,通过该方法可以形成庞大的氟代烷基,例如i -C 3 F 7,t -C 4 F 9,据报道,c -C 6 F 11可以很容易地引入到磷(III)中心。这些方法共同提供了一种生成R 3− n P(R f)n类型的P(III)系统的方法,该系统具有广泛的空间和电子特性。

Di-isopropyl(trichlorosilyl)phosphane (2a) is less reactive towards Me3SnCl, tBu2PSnMe2Cl (5b) and Me2SnCl2 than di-isopropyl(trimethylsilyl)phosphane (3a). Compound 3a reacts with each of the organotin chlorides to provide iPr2PSnMe3 (1a), (iPr2P)2SnMe2 (6a) or mixtures of (tBu2P)n(iPr2P)2−nSnMe2 (n=0, 1, 2: 6a, c, b), but 2a reacts with Me2SnCl2, providing only iPr2P(μ-SnMe2Cl)2Cl (4a), which has
A simple route to azaborinylphosphines: isoelectronic B–N analogues of arylphosphine ligands

Azaborinylphosphines are readily prepared by the reaction of silylphosphines with a chloroborane under mild conditions; they are shown to contain P–B bonds that are sufficiently robust to allow these ligands to be used in homogeneous catalysis.
