Syntheses and properties of aminomethyl complexes of manganese and rhenium

Abstract

The interaction of a range of aminomethyltrimethyltins with carbonyl halides of manganese and rhenium has afforded the yellow volatile compounds [(η²-R₂NCH₂)M(CO)₄](M = Mn and Re). In these complexes the aminomethyl ligand functions as a formally three-electron donor, and the ligand is removed by halogen to form the corresponding methyleneammonium halide.
