Abstract

Molybdenum stannyl complexes ligated by poly(methimazolyl)borate ligands are accessible via complementary strategies involving oxidative addition of either Ph3Sn{HB(mt)3} (mt = methimazolyl) or[Me 2-Sn{H2B(mt)2}]Cl to molybdenum(0) precursors or alternatively via reactions of halostannanes with the salts Na[Mo(CO) 3{HxB(mt)4-x}] (x = 1, 2). One example provides a novel complex in which the H2B(mt)2 ligand bridges both molybdenum and tin, thereby providing a model for an intermediate in the oxidative addition protocol.
