Two new processes for the preparation of sec. phosphine sulfides which involve reaction of dialkylamino-dialkyl or diaryl phosphines with hydrogen sulfide, and of dialkylthionophosphonates, (RO)2P(S)H, with GRIGNARD or organolithium reagents, respectively, are described. The addition of sec. phosphine sulfides to olefins and the condensation of sec. phosphine sulfides with N-hydroxymethyldialkylamines

An atom-economic green synthesis of tertiary phsophine sulfides has been developed based on catalyst- and solvent-free addition of secondary phosphine sulfides to diverse terminal and internal alkenes (hept-1-ene, cyclohexene, styrenes, allyl alcohol, vinyl ethers, vinyl sulfides, vinyltrimethylsilane, 1-vinylimidazoles, vinyl acetate). The reaction proceeds under mild conditions (80 °C, without solvent

sulfides readily undergo both phosphinoyl transfer and cyclopropane ring closure just like their phosphine oxide counterparts. The obtained data show that phosphine oxides are easily lithiated and undergo phosphoryl transfer much more readily and faster than phosphine sulfides and phosphine boranes. The observations suggest that it would be possible to perform reactions involving phosphine oxides in the presence

new type of ring-chain anionotropic tautomerism for cyclic thiaphospholanium bromide 2A and isomeric phosphine sulfide 2B was investigated. Both of the tautomers were isolated in crystalline form. Their structures were proved by IR, Raman, 1H, 31P NMR spectroscopy and X-ray analysis. In solution the equilibrium position doesn't depend on the kind of dissolved tautomer. The effect of the solvent. concentration
摘要 研究了环状硫磷溴化物2A和异构硫化膦2B的一种新型环链阴离子互变异构现象。两种互变异构体均以结晶形式分离。它们的结构已通过红外、拉曼、1H、31P 核磁共振光谱和 X 射线分析证明。在溶液中,平衡位置不取决于溶解的互变异构体的种类。溶剂的作用。研究了平衡 2A ⇋ 2B 上的浓度和温度以及互变异构体的互变动力学。
