Abstract

Abstract The prolonged photo-Arbuzov reaction (3 weeks, Hg lamp) of 1, 3, 5-trichloro- benzene with a large excess of trimethyl phosphite (as a solvent) at 50 gives moderate yields of dimethyl (3, 5-dichlorophenyl) phosphonate (1; 14.5%), tetramethyl (5-chloro-1, 3- phenylene) bis [phosphonate](2; 35.4%), and hexamethyl (benzene-1, 3, 5-triyl) tris [phosphonate](3; 30.1%). The products can be separated by fractional distillation. Acid ...
