Abstract

Results Thequaternaryphosphoniumionsused in thephotolysis experiments are shown in Scheme I. Tetrafluoroborate and chloride (in case of la and lg also other halides) ions were selected as examples of nonoxidizable and oxidizable counterions Y-. Acetonitrile and methanol were used as solvents of greatly different
