Perlikowska, Wieslawa published the artcileLithiation of diethyl trichloromethylphosphonate and the transformations of the α-lithiated derivative, Product Details of C5H10Cl3O3P, the publication is Journal of the Chemical Society, Perkin Transactions 2: Physical Organic Chemistry (1996), 2611-2613, database is CAplus.
The lithiation of di-Et trichloromethylphosphonate below -100° leads to a stable α-lithiated derivative, but at temperatures of ∼-80° the lithiation is accompanied by spontaneous reactions leading to tetra-Et (chloromethylene)bisphosphonate as the exclusive product. Possible mechanisms of the reaction are discussed. Thus, treating Cl3CPO3Et2 with BuLi and anhydrous LiCl in Et2O at -105° gave 74% Cl2CHPO3Et2, whereas reaction with BuLi in Et2O at -80° gave 95% ClCH(PO3Et2)2.
