THERMOLYSIS OF ACYCLIC AZOALKANES: SIMULTANEOUS OR STEPWISE C-N HOMOLYSIS?
Engel,Gerth
, p. 6849 - 6851 (2007/10/02)
Irradiation of several trans- alpha , alpha -dimethylallylazoalkanes produces the thermally labile cis isomers. Among their thermolysis products, we have found 'turnaround' azoalkanes (TA) corresponding to recombination of alkyldiazenyl radicals at the primary end of the dimethylallyl radical. The amount of TA decreases when R multiplied by (times) is a better radical, suggesting a competition between beta scission of RN equals N multiplied by (times) and recombination to give starting azoalkane and TA. A stepwise, internal-return mechanism correctly predicts when formation of TA will be important.
