Abstract
Half-sandwich nitrosyl complexes Cp*M(NO)I2 (M = Mo, or W) react with dithiocarbamates (NaS2CNMe2 and NaS2CNEt2) in THF to form of complexes: Cp*Mo(NO)I (S2CNMe2) (1), Cp*Mo(NO)I(S2CNEt2) (2), Cp*W(NO)I(S2CNMe2) (3) and Cp*W(NO)I(S2CNEt2) (4) in high yields. Treatments of Cp*M(NO)I2 (M = Mo, W) or [CpMo(NO)I2]2 with phosphinodithioate (NaS2PMe2) and phosphorodithioate [(NH4)S2P(OMe)2] result in complexes: Cp*Mo(NO)I(S2PMe2) (5a), CpMo(NO)I (S2PMe2) (5b), Cp*Mo(NO)(S2PMe2)2 (6a), CpMo (NO) (S2PMe2)2 (6b) and Cp*Mo(NO)I[S2P(OMe)2] (7), Cp*W(NO)I(S2PMe2) (8), Cp*W(NO) I[S2P(OMe)]2 (9). Treatment of (5a) and (5b) with an excess of NaS2PMe2 gives (6a) and (6b). The complexes have been characterized by their elemental analyses, i.r., 1H, 13C-n.m.r. and by EI-MS spectrometry.
