A reaction of aryl ketenes with 1-arylmethylidenepyrazolidin-1-azomethine imines, generated by the diaziridine ring opening in 6-aryl-1,5-diazabicyclo[3. 1.0]hexanes catalyzed with Et2O?BF3, leads to 1,2-bis(phenylacetyl) pyrazolidine, 2-arylacetyl-1-arylidenepyrazolidin-1-ium chlorides, or a representative of 1,5-diazabicyclo[3.3.0]octan-2-ones, viz., 4-(4-eth-oxyphenyl)-3,3-diphenyl-1,5-diazabicyclo[3.3.0]octan-2-one, depending on the reaction conditions and the structure of the starting compounds. A mechanism suggested earlier for the transformation of 1,5-diazabicyclo[3.1.0] hexanes in the reaction with ketenes was confirmed.
