Synthesis of Some Dialkyl Bromo-Substituted Benzyl Phosphonates

Arbuzov reaction of bromo-substituted benzyl bromides and trialkyl phosphites in benzene gave high yields of dialkyl bromo-substituted benzyl phosphonates, and —CH₂CH₂CH₂CH₃). The structural assignments of these phosphonates were confirmed by ¹H nmr, ¹³C nmr, ir and mass spectral analysis.
