Acrilamide and N,N-dimethylacrylamide complexes. II. N-protonation and N-bonding to some transition metal perchlorates and tetrafluouroborates

Abstract

Simple molecular orbital calculations were carried out on acrylamide (AA) and N,N-dimethylacrylamide (DAA), the results indicating that molecules of lower energy are formed upon coordination through N rather than O. Protonation studies in FSO 3H by nmr show that both AA and DAA are N-protonated, in agreement with the m.o. calculations. Complexes of some first row transition metal perchlorates and tetraflouroborates exhibit attachment through nitrogen for the AA but O-coordination for the DAA molecules. Steric factors are invoked to explain the different modes of bonding.
