Reaction of pentacarbonyl(alkoxyalkylcarbene)chromium complexes with N,N-dimethylformamide dialkyl acetals: synthesis of pentacarbonyl-(alkoxyenaminocarbene) and -(dialkoxycarbene)chromium complexes
Abstract
On treatment of the carbene complexes (1a–f) with N,N-dimethylformamide dialkyl acetals (DMF-DAA)(2a–d) as electrophiles, the nature of the products, (3) or (4), depends on the structure of the starting carbene complexes.
