资源简介:
The C−S bond cleavage in the alkynethiolate ligand of the compound Li[Fe3(μ3-SC⋮CtBu)(CO)9] (1a) takes place in its reaction with [AuClPR3] (R = Ph, iPr), affording the complexes [Fe3Au(μ4,η2-C⋮CtBu)(CO)9(PR3)] (R = Ph (3a), iPr (3b)). The gold fragment displays an unexpected bonding mode, and a fast and reversible process of oxidative addition/reductive elimination of the Au−C bond has been observed in solution.
