The cyclic bis azo compounds VI (n= 8, lO) have been prepared and characterized. A study of the decomposition of VI, n= 8, in xylene at 120'resulted in the isolation and characterization of VII, a twenty-membered carbon ring. From the rate data obtained, it is suggested that both azo linkages in VI, n= 8, do not decompose at exactly the same rate. Decomposition of VI,%= 8, in styrene gave no polystyrene under conditions in which a ...
