Novel heterobimetallic coordination of the H 2 B(mt) 2 ligand: the complex [Mo(SnMe 2 Cl)(CO) 3 { μ-S:κ 3 - H,S,S -H 2 B(mt) 2 }] (mt = methimazolyl)

Foreman, MarkHill, AnthonySmith, MatthewTshabang, Never2015-12-130276-7333http://hdl.handle.net/1885/81279Molybdenum 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.Keywords: Addition reactions; Complexation; Coordination reactions; Oxidation; Ligands; Oxidative addition; Reaction intermediates; MolybdenumNovel heterobimetallic coordination of the H 2 B(mt) 2 ligand: the complex [Mo(SnMe 2 Cl)(CO) 3 { μ-S:κ 3 - H,S,S -H 2 B(mt) 2 }] (mt = methimazolyl)200510.1021/om050778z2015-12-11
