Pyrolysis of t-butyl diethoxyphosphinylacetate

Abstract

The pyrolysis of tert-Bu diethoxyphosphinylacetate at 150?was investigated. Examination of the IR, 1H NMR, GC, pKa and GC-MS of the reaction mixture indicated the presence of Et diethoxyphosphinylacetate, Et ethoxyhydroxyphosphinylacetate, Et dihydroxyphosphinylacetate, diethoxyphosphinylacetic acid, ethoxyhydroxyphosphinylacetic acid, di-Et methylphosphonate and monoethyl methylphosphonate. Et diethylphosphinylacetate and di-Et methylphosphonate were isolated from the product mixture The mechanism of pyrolysis of tert-Bu diethoxyphosphinylacetate is also discussed. The influence of the temperature of reaction on the pyrolysis of tert-Bu diethoxyphosphinylacetate has been investigated.
