文摘
Removal of an acetato ligand from dirhodium(II) acetato complexes with thioethers of thegeneral structure [Rh2(
-OAc)4(RSCH2Z)2] yields the cationic complexes [Rh2(-OAc)3(RSCH2Z)2](BF4) (R = Me, Ph; Z = C(O)OEt, CH2C(O)OMe). The methylthio complex withZ = C(O)OEt has been structurally characterized and found to exhibit an unusual bidentateO-S coordination of the oxo thioether ligands. Preliminary tests indicate that the complexis a promising catalyst of the silylformylation or hydrosilylation of 1-hexyne with dimethylphenylsilane.
