Building of dithiocarbamate and dithiocarbimate ligands within a heterobimetallic core
Abstract
Heterobinuclear anions [MnRe(CO)6(μ-S)(μ-SCPR3)]2−
(2) undergo selective protonation and electrophilic addition of dimethylthiocarbamoyl or isothiocyanate to afford, respectively, neutral [MnRe(CO)6(μ-S2CNMe2)(μ-S2CPR3)]
(3) containing μ2-(S,S′) dithiocarbamate, or anionic [MnRe(CO)6(µ-SC(S)NR′){µ-SC(H)PR3}]−
(4) containing μ2-(N,S)-dithiocarbimate. The terminal sulfur in the latter can be methylated with MeI or metallated with [AuCl(p-tolyl)3] to give neutral dithiocarbimato complexes 5 or 6. The structures of 3a
(R = Pri), 5a
(R = Pri, R′= Et), and 5c
(R = Pri, R′= Ph), have been determined by
