Abstract

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 of 6b with 1 equiv of MeOH afforded methoxysilylsulfanyl complex Cp*(OC)3W(SSiPh2OMe) (7) and [H·DMAP]TFPB (8).
