[摘要]：Highly labile SG1-based alkoxyamines were synthesized using the photodecompn. of both azo compds. and dithiocarbamates. The former method was a straightforward procedure to obtain the alkoxyamines, but a high [azo]/[nitroxide] ratio is needed. The latter method required only a stoichiometric amt. of dithiocarbamate and allowed the recovery of the disulfide after irradn. This enabled combination of the two methods in a process where only 0.75 equiv of azo compd. is needed and where sulfurous compds. acted only as intermediates.
