摘要：

The reaction of [(RhCp*)(2)(mu-CH2)(2)(mu-SH)]-(BPh4) (1(BPh4); Cp* = eta(5)-C5Me5) with 1 equiv of dimethyl acetylenedicarboxylate gives the substituted ethenethiolate complex [(RhCp*)(2)(mu-CH2)(2){mu-SC(COO-Me)=CH(COOMe)}](BPh4 (2(BPh4). Complex 2 reacts further with another alkyne to form the butadiene complex [(RhCp*)(2){eta(2):eta(2)-mu-CH2=C(COOMe)C(COOMe)=CH2} {mu u-SC(COOMe)=CH(COOMe)}](BPh4) (3. BPh4)), which results from the C-C bond formation using two mu u-CH2 groups and the alkyne.
