New Synthesis of Diethyl Auylphosphonates and Diethyl Alkenylphosphonates

Abstract
Organometallic reagents readily added to diethyl l-(trimethylsilyl) vinylphosphonate 1 by virtue of the polarizing silyl group. Quenching with acetic acid, methyl iodide, and carbonyl compounds gave synthetically useful diethyl alkylphosphonates 6 and diethyl alkenylphosphonates 8 respectively.
