A visible-light-induced metal-free catalytic system was developed for the synthesis of arylphosphonates starting from arylhydrazines and trialkylphosphites. By using the inexpensive eosin B as catalyst, sub-stoichiometric amounts of DABCO, and ambient air as oxidant, diverse arylphosphonates were obtained under visible-light irradiation. Notably, this catalytic system is suitable for gram-scale reaction by utilizing sunlight as an illumination source.

A highly efficient, AgI/K2S2O 8-mediated regioselective phosphonation reaction has been developed by using electron-deficient directing groups. These phosphonation reactions were performed with N,N-dialkylbenzamides, N,N-dialkylbenzenesulfonamides, and nitrobenzene. This method has a broad substrate scope and offers facile construction of C-P bonds. Copyright

Synthesis of new aryl / alkyl phosphonates 3a-j has been accomplished via a Michaelis- Arbuzov-type rearrangement by the reaction of aryl / alkyl halide (1a-j) with triethyl phosphite (2) in dry toluene at reflux temperature. Products 3a-j were characterized by IR, 13C and 31P NMR and their antibacterial activity was evaluated.
