摘要：

Treatment of the 16-valence-electron complexes Cp*M(NO)(aryl)2 (Cp* = eta5-C5Me5; M = Mo, W; aryl = phenyl (Ph), p-tolyl) with the heterocumulenes carbon disulfide, p-tolyl isocyanate, and carbon dioxide leads to the eta2-thiocarboxylate, eta2-amide-, and eta2-carboxylate-containing complexes, respectively, in 10-65% isolated yields. Furthermore, Cp* W(NO) (eta2-S2C-Ph)(Ph) (1) reacts with trimethylphosphine to form Cp*W(NO)(eta2-S2C(PMe3)Ph)(Ph) (10), which contains a zwitterionic phosphonium betaine ligand. The solid-state molecular structure of 10-CH2Cl2 has been established by a single-crystal X-ray crystallographic analysis. Crystal data for Cp*W(NO)(eta2-S2C(PMe3)Ph)(Ph). CH2Cl2: monoclinic, a = 8.482(1) angstrom, b = 27.410(2) angstrom, c = 13.054(3) angstrom, beta = 92.02(1)degrees, Z = 4, space group P2(1)/n (No. 14), R(F) = 0.029, and R(wF) = 0.027 for 5374 reflections with I greater-than-or-equal-to 3sigma(I).
