The Beckmannrearrangement of oximesulfonates by Grignard reagents provides an efficient and general entry to α-alkyl- and α,α-dialkylamines in good yields.
A new synthetic method of imidoyliodides has been devised which involves the Beckmann rearrangement of oxime derivatives with trimethylsilyl iodide or diethylaluminum iodide. This allows a one-pot procedure for a α-arylation of amines in synthetically useful yields.
