The products and the kinetics of the thermolysis of the title compounds 3 and 5 were investigated. Like the trans ‐isomers, the cis ‐azo compounds also undergo homolytic decomposition without accompanying cis‐trans ‐isomerization. The observed structure‐reactivity relationships are discussed. On irradiation of trans ‐tetra‐ tetr ‐butylazomethane ( trans ‐ 5 ) at 60–120°C in benzene or chlorobenzene an almost quantitative yield of 1,1,2,2‐tetra‐ tert ‐butylethane is obtained.
