N-Alkyl a-diazo-g-butyrolactams previously found to be unstable and undergo unproductive dimerization to bis-hydrazones, were successfully converted immediately to various X-H insertion products with alcohols, aromatic amines and thiols via an in situ RhII-catalyzed reaction. With aliphatic amines or unreactive, sterically hindered anilines, the reaction tends to yield enamine adducts.
Keywords: N-alkyl 2-pyrrolidones; in situ reaction; stability of diazo compounds; RhII-catalyzed insertion reactions
