Abstract

The reactivity of the secondary phosphide KP(Pr)Ter (1) (Ter = 2,6-bis-(2,4,6-trimethylphenyl)phenyl) toward small molecules is reported. Phosphide 1 displays distinct nucleophilic character and reacts selectively with chalcogens (S, Se), heteroallenes (CO, PrNCS), and an acyl chloride (AdCOCl) to give the corresponding dichalcogenophosphinates (2a, 3), phosphanyl formate (5), thiocarbamoylphosphane (6a), or acylphosphane (7a), respectively. Furthermore the follow-up chemistry of these products was investigated. 2a was converted to a PSPS ligand (2b) which forms a Au(I) complex (2c) with (MeS)AuCl. Likewise, a gold complex of 7a was prepared. All species were isolated and fully characterized.

摘要

报道了二级膦化物KP(Pr)Ter (1)（Ter = 2,6-双-(2,4,6-三甲基苯基)苯基）与小分子的反应活性。膦化物1表现出独特的亲核特性，分别与硫属元素（S、Se）、杂丙二烯（CO、PrNCS）和酰氯（AdCOCl）选择性反应，生成相应的二硫属元素次膦酸酯（2a、3）、膦酰基甲酸酯（5）、硫代氨基甲酰基膦烷（6a）或酰基膦烷（7a）。此外，还研究了这些产物的后续化学反应。2a被转化为一种PSPS配体（2b），它与(MeS)AuCl形成金（I）配合物（2c）。同样，制备了7a的金配合物。所有物种均被分离并进行了全面表征。
