Abstract
The cycloaddition reactions of diphenylketene to some C=N heterocycles have been reexamined and the adducts are assigned oxazinone (3 or 4) rather than amido ketone structures 2. The reaction of 4 with hydrazine yielded pyrazolinone 7, whereas sodium methoxide produced the ring-opened ester 6.
