Abstract

Irradiation of aromatic carbonyl compounds in hexamethylphosphoric triamide (HMPA) resulted in the cross-coupling of ketyl radicals with the HMPA-derived radical generated via hydrogen abstraction from it. The results on acetolysis, methanolysis, and the reaction with thionyl chloride of the resulting coupling products are described.
