Abstract
The reaction of [PPh4]2[WS4] in CH3CN with excess n-propylbromide or n-butylbromide gave alkylthiolatotrithiotungstate complexes, [PPh4][WS3(SR)] (1: R=n-propyl; 2: R=n-butyl). The analogous reaction with 1-bromomethyl-4-chloromethyl-benzene afforded a benzylthiolatotrithiotungstate complex, [PPh4][WS3(SCH2C6 H4CH2Cl-4)] (3), whereas the reaction with 1,4-bis-bromomethyl-benzene led to isolation of a dinuclear complex [PPh4]2[WS3(μ-SCH2C6H4CH2S)WS3] (4). Complexes 1–4 were characterized spectroscopically and the crystal structures of 1/2·½C6H6 and 3 have been determined by X-ray diffraction.
标题:摘要
[PPh4]2[WS4]在CH3CN中与过量的正丙基溴化物或正丁基溴化物反应,得到了烷基硫代三硫代钨酸盐配合物,[PPh4][WS3(SR)] (1: R=正丙基; 2: R=正丁基)。类似地,与1-溴甲基-4-氯甲基苯反应得到苄基硫代三硫代钨酸盐配合物,[PPh4][WS3(SCH2C6 H4CH2Cl-4)] (3),而与1,4-双溴甲基苯反应导致了双核配合物[PPh4]2[WS3(μ-SCH2C6H4CH2S)WS3] (4)的分离。配合物1-4经光谱表征,配合物1/2·½C6H6和3的晶体结构已通过X射线衍射测定。
