Reactions of 1-aminocyclopentenes 1 with acyl aryldiazenes 2 give 1:1 enaminic adducts 3 and 4, or 1,3,4-oxadiazines 5.Isolation of these products was not always possible in the reactions of 1-(piperidin-1-yl)- and 1-(pyrrolidin-1-yl)-cyclopentene.Acidic hydrolysis gave 2-(N-acyl-N'-aryl)hydrazinocyclopentanones 6 or 2-arylaminocyclopentenones 8, depending upon the amino moiety and the cyclic or open chain nature of the adducts.
