摘要

I able to prepare the tert-butylurea 5 by reaction with tert-butyl isocyanate and amine hydrochloride. The latter derivative we previously prepared by cyclization of propargylurea 6 and hydrolysis of the corresponding imidazolindione 7.'The monomer can also be coupled to form the azo compound (4) by reaction with IF,. This keto diazene was prepared as part of our continued interest in radical stabilizing effects2 and ita rate of thermal decomposition ...
