Abstract

The reaction of [(RhCp*)2(μ-CH2)2(μ-SH)]-(BPh 4) (1(BPh4); Cp* = η5-C5Me5) with 1 equiv of dimethyl acetylenedicarboxylate gives the substituted ethenethiolate complex [(RhCp*)2(μ-CH2) 2{μ-SC(COOMe)=CH(COOMe)}](BPh4) (2(BPh4)). Complex 2 reacts further with another alkyne to form the butadiene complex [(RhCp*)222-μ-CH 2=C(COOMe)C(COOMe)=CH 2}{μ-SC(COOMe)=CH(COOMe)}](BPh4) (3· BPh4)), which results from the C-C bond formation using two μ-CH2 groups and the alkyne.
