Abstract
Cationic eta2-thiocarbene complexes of molybdenum and tungsten [CP(CO) PMe3M=C(R) Me][BF4] (R = Me, Ph, Tol) add N3COOMe to the electron rich metal carbon double bond to yield the corresponding bicyclic system. The products have been characterized by H-1, C-13, P-31 NMR, IR and ma ss spectra. The crystal structure of 4b has been determined: space gro up P2(1)/n with a = 1749.9(7), b = 827.9(1), c = 1846.8(7) pm and Z = 4.
