Abstract

Dimethyl [(substitutedphenyl)(6-oxo6λ5dibenzo [d, f][1, 3, 2] dioxaphophepin-6-yl) methyl] phosphonates (5a–j) were synthesised through a three step process involving preparation of dimethyl hydroxy (substitutedphenyl) methylphosphonates (4a–j) and their reaction with 6- bromodibenzo [d, f][1, 3, 2] dioxaphosphepine (2) in dry toluene in the presence of triethylamine at 50–60° C. Tetramethylguanidine (TMG) as a catalyst was found to ...
