on cluster, RR′Si(Cl)CCo3(CO)9, is described. The alkoxy derivatives react with i-Bu2AlH or BF3 · Et2O to give the corresponding silicon hydride or fluoride. Reaction of methylidynetricobalt nonacarbonyl with optically active silanes of germane gave the optically active cluster complexes R1R2R3M*CCo3(CO)9 (M* = Si, Ge). These compounds react with phosphine to give the monosubstituted R1R2R3M*CCo3(CO)8(PR3
描述了含有九碳三羰基碳原子团RR'Si(Cl)CCo 3(CO)9的手性氯硅烷的制备和醇解。烷氧基衍生物与i-Bu 2 AlH或BF 3 ·Et 2 O反应,得到相应的氢化硅或氟化硅。亚甲基炔丙基九碳羰基与锗烷的旋光性硅烷反应,得到旋光性簇络合物R 1 R 2 R 3 M * CCo 3(CO)9(M * = Si,Ge)。这些化合物与膦反应生成单取代的R 1 R 2R 3 M * CCo 3(CO)8(PR 3(M * = Si,Ge)。非对映异构体在MePhSi(Obornyl)CCo 3(CO)9配合物的情况下已得到解决。
