leading to the dimer (NacNacGa)2(μ-S)(μ-CNPh) and the cyclization product NacNacGa(S2C═NPh). These compounds were characterized by multinuclear NMR spectroscopy and X-ray crystal structure analyses. Oxidative addition of S═PPh3 occurs at elevated temperatures and results in the known dimer [NacNacGa(μ-S)]2.
