The thermal behavior of bis (1-acetoxy-1, l-dicyclo-propylmethy1) diazene (3) is as expected, and it extrudes nitrogen. However, the products, as analyzed by NMR, show considerable ring opening. The first order rates of decomposition are listed in Table 1, 17 and the results are in accord with earlier studies on rate enhancements in formation of cyclopropylcarbinyl radicals. 2J8 The rate acceleration of 3 over the corresponding ...
