Aluminum Chloride Catalyzed Oligomerization of Ketene Imines and Incorporation of Carbon Dioxide in an Open-Chain Dimer

Article abstract of DOI:10.1021/jo00186a025

Aluminum trichloride and diethylaluminum chloride induce cyclodimerization and cyclotrimerization of three C,C-dimethylketene N-arylimines to quinazoline, azetidine, and triazine derivatives.The product distribution depends on the catalyst, the molar rati
