The first examples of the hydrophosphination of alkyl vinyl sulfides and selenides are described. The reaction of secondary phosphines (R 1 ) 2 PH 1-3 with vinyl chalcogenides CH 2 =CHXR 2 4-9 proceeds readily under radical initiation to give in anti-Markovnikov mode regiospecifically the corresponding organylchalcogenophosphines (R 1 ) 2 PCH 2 CH 2 XR 2 10a-h in high yields.

Abstract The reaction of [Mo3S4(Tu)8(H2O)]Cl4·4H2O (Tu is thiourea) with (PhCH2CH2)2-PCH2CH2SeC5H11) (PSe) followed by purification on a chromatographic column packed with silica gel using a saturated solution of KPF6 in acetone as an eluent results in the formation of [Mo3S4Cl3(PSe)3]PF6 (I) in a yield of 44%. Compound I is characterized by X-ray diffraction analysis, 1H, 31P1H}, and 77Se NMR spectroscopy
摘要 [Mo 3 S 4(Tu)8(H 2 O)] Cl 4 ·4H 2 O(Tu是硫脲)与(PhCH 2 CH 2)2 -PCH 2 CH 2 SeC 5 H 11)(PSe)的反应然后在装有硅胶的色谱柱上纯化,使用KPF 6在丙酮中的饱和溶液作为洗脱液,可以形成[Mo 3 S 4 Cl 3(PSe)3 ] PF 6(I),产率为44 %。化合物IX射线衍射分析,1 H,31 P 1 H}和77 Se NMR光谱,IR光谱,UV-Vis光谱,循环伏安法和电喷雾电离质谱法的表征。在室温下,在化合物I的溶液中形成了三个PSe配体的配位模式不同,这三个PSe配体可以通过一个(磷)或两个(磷和硒)供体原子与钼结合。对于在结构上与类似类型的PS配体相似的化合物,未观察到此行为。复杂的我 在二苯硅烷的作用下,证明硝基苯还原为苯胺比其具有PS配体的类似物具有更高的催化活性。

Addition reactions with complete atom economy conform to the “green chemistry” principles, and they constitute now a purposefully and dynamically developing field of organic chemistry [1–7]. Of particular interest are atom-economic processes that can be readily accomplished without catalyst and solvent [8–10]. In recent years, convenient methods for carbon–phosphorus bond formation via noncatalytic
