Abstract

Ten new complexes, [M(CO)5(amsh)] [M = Cr; (1a), Mo; (2a), W; (3a)], [Re(CO)4Br(amsh)] (4a), and [Mn(CO)2(amsh)Cp] (5a) and [M(CO)5(msh)] [M = Cr; (1b); Mo, (2b); W, (3b)], [Re(CO)4Br(msh)], (4b), and [Mn(CO)3(msh)], (5b), have been synthesized by the photochemical reaction of the metal carbonyls [M(CO)6] (M = Cr, Mo, and W), [Re(CO)5Br], and [Mn(CO)3Cp] with acetonemethanesulfonylhydrazone (amsh) and methanesulfonyl hydrazine (msh). The complexes have been characterized by elemental analyses, mass spectrometry, FT‐IR and 1H NMR spectroscopy. The spectroscopic studies show that amsh and msh behave as a monodentate ligands coordinating via an imine N donor atom in (1a)–(5a) and a hydrazine N donor atom in (1b)–(5b).
