The principal products of the reaction of the N-methylnitrone (1a) with dimethylketene have been identified as the dioxolane derivative (6) and its hydrolysis products (7).Fluoren-9-yl isocyanide appears to be an intermediate in this reaction.Ketene reacts with nitrone (1a) and its N-ethyl and N-isopropyl analogues to give the cyclobutanedione (15) as the only isolated product.Compound (15) has been synthesized from fluoren-9-ylidenemalonic acid.
