Abstract
Reaction of two equivalents of α-bromo- N-methoxyalkanimines with tetra- n-butylammonium tricarbonylnitrosylferrate gave a reductively dimerized product of α-bromoimines, in which the reaction ( η 3-1-azaallyl)dicarbonylnitrosyliron complexes are intermediates for the dimerization reaction of α-bromoimines. Variable temperature 1H NMR study of the η 3-1-azaallyl iron complex thus obtained demonstrated that the bonding of the azaallyl ligand is fluxional at room temperature, but is fixed below 233 K.
