摘要

X'E xanthyl radical amidoethylated xanthene in one case (R= Me) is evidence for a cross combination of X'with the radical formed by homolytic ring opening. Cross combination is also a likely path for R= H (no cis-trans isomerism), in addition to reductive ring opening. cis- Aziridines with dimethylcarbamoyl on nitrogen do not react via SET since the ketyl is not stabilized and therefore difficult to generate. Carbonyl attack on both types of ...
