were determined, and 1 was found to adopt an unusual, compact conformation, rather than the more extended conformation observed in a related system. The sulfuration of 1 is 10000 times slower than the corresponding sulfuration of triphenylphosphine, and the rate-determining step for the former reaction appears to be the phosphine inversion (ΔG⧧inv = 34.8 kcal/mol). Desulfurization of 4 with hexachlorodisilane
