Abstract

PART I: cis- and trans-1,2-Diaminocyclohexanes:

Work initiated in these laboratories by Reims and Buchman on the stereospecific conversion of cis- and trans-cyclohexane-1,2-dicarboxylic acids to the corresponding diamines has been extended. cis- and trans-1,2-Diaminocyclohexanes have been characterized by measurements of densities, refractive indices, acid constants and melting points and by preparations of both side-chain and cyclic derivatives.

PART II: A study of the tertiary amine precursors of pirylene:

The observation of Sargent, Buchman and Farquhar, that the Hofmann degradation of N,N-dimethyl-[alpha]-bromomethylpyrrolidinium bromide does not give a single C7H13N amine, but a mixture of isomeric tertiary amines has been confirmed. The components of the C7H13N amine mixture have been identified as follows:

(1) 1-dimethylamino-4-pentyne

(2) 1-dimethylamino-2,4-pentadiene

(3) 1-dimethylamino-3,4-pentadiene

(4) 1-dimethylamino-3-pentyne

(5) 1-dimethylamino-1,3-pentadiene.

Components (2), (4) and (5) have been isolated and characterized. Components (1) and (3) were detected by infrared spectroscopy.

A probable course of formation of the C7H13N amine mixture from N,N-dimethyl-[alpha]-bromomethylpyrrolidinium bromide is discussed.
