Abstract

Abstract: Triplet EPR spectra have been observed for four isomers of quinolylmethylene. These divalent-carbon species were generated by photodecomposition of 3-, 4-, and 8- quinolyldiazomethane and of 5, 6-benzopyridotriazole at cryogenic temperatures in frozen solutions. For each of the three quinolylmethylenes derived from diazomethanes the EPR spectra indicate the presence of two similar but nonidentical triplets, which are assigned to ...
