通过用Ph 3CTFPB从硅硫烷基配合物Cp *（OC）3 WSSiR 2 H（5）中提取H，然后加入DMAP，分离得到阳离子硅硫醚配位过渡金属配合物[Cp*（OC）3 W {S <$SiR2（DMAP）}]TFPB（R = Me（6a），Ph（6 b），Cp* = η5-C5 Me 5，DMAP = 4-（二甲氨基）吡啶，TFPB-= B{3，5-（CF 3）2C 6 H3}4-）. 6 b与1当量甲醇反应，得到甲氧硅烷基硫烷基配合物Cp*（OC）3 W（SSiPh 2 OMe）（7）和[H·DMAP]TFPB（8）。
The cationic silanethione-coordinated transition-metal complexes [Cp*(OC)3W{S═SiR2(DMAP)}]TFPB (R = Me (6a), Ph (6b), Cp* = η5-C5Me5, DMAP = 4-(dimethylamino)pyridine, TFPB–= B{3,5-(CF3)2C6H3}4–) were isolated by H–abstraction from silylsulfanyl complexes Cp*(OC)3WSSiR2H (5) with Ph3CTFPB, followed by the addition of DMAP. The reaction of6bwith 1 equiv of MeOH afforded methoxysilylsulfanyl complex Cp*(OC)3W(SSiPh2OMe) (7) and [H·DMAP]TFPB (8).
