Berte-Verrando, Sylvie published the artcileGeneral synthesis of α,α-dideuteriated phosphonic esters, Product Details of C5H10Cl3O3P, the publication is Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) (1994), 821-4, database is CAplus.
A range of α,α-dideuteriated phosphonic esters has been prepared by deuteriolysis of α-silylated α-phosphonylated carbanions with D2O as deuterium source. In most cases, incorporation of deuterium is greater than 95% and the yields are good to excellent. The title products are potential trace compounds in many biol. and industrial applications.
