Development of group 6 dearomatization agents

초록

A series of complexes having the general formulas [TpM(NO)(L)Br] and [TpmM(NO)(L)Br]BF 4 (M = Mo or W and L = a moderate σ-donor) have been prepared. Variations in L provide access to M(I) complexes having a broad range of electronic and steric properties. Reduction of a limited number of these complexes in the presence of aromatic molecules produces novel complexes with the general formula [TpM(NO)(L)(η 2-aromatic)] n+ (n = 0, 1). © 2006 American Chemical Society.
