Formation and Reaction of Azomethine Ylide by the Reaction of Cu(acac)2ketocarbenoids with 1,1-Diphenylmethanimine

Article abstract of DOI:10.1246/cl.1994.81

The reaction of α-diazacarbonyl compounds with 1,1-diphenylmethanimine in the presence of Cu(acac)2 afforded the corresponding N-substituted imines in general together with pyrrolidine and 1,4,6-dioxazocine derivatives (in the reaction of α-diazo-4-chloroacetophenone) and 1,1-diphenyl-2-(4-nitrobenzoyl)ethylene (in the reaction of α-diazo-4-nitroacetophenone) through azomethine ylides.
