Abstract
Deprotonation of the double-bridging mu(2)-CH2 complex [Rh2Cp2(mu(2)- CH2)(2)(mu(2)-SH)](BPh4) (Cp = eta(5)-C5Me5 with [Rh2Cp2*(mu(2)-OH)(3 )](BPh4) led to the isolation of the trirhodium mu(3)-S complex [Rh3Cp 3(mu(3)-eta(2)-parallel to-C2H2) (mu(3)-S)](BPh4)(2), including an ac etylene ligand generated by a unique C-C bond coupling and deprotonati on of two mu(2)-CH2 groups. The dynamic property of the acetylene comp lex in both solution and the solid state was studied by variable-tempe rature H-1, C-13, and CP/MAS C-13 NMR spectroscopy.
