Abstract
N,N-Dichlorocyclohexylamine-1-14C has been treated with sodium methoxide in methanol and then with hydrochloric acid to yield 14C-labeled 2-aminocyclohexanone hydrochloride. Successive degradations have revealed that practically all the 14C activity was found in the carbonyl carbon of the original aminoketone. From the 14C distribution, it has been concluded that the reaction is essentially the same as that proposed for the Neber rearrangement. As a part of the degradation of 2-aminocyclohexanone, deaminative diazotization was employed to obtain cyclopentanecarboxylic acid together with other minor products. The 14C tracer work revealed that the carbonyl group of the acid is originated from the carbonyl group of the 2-amino-ketone.
