Általános leírás
Ethyl phenylphosphinate is an organophosphorous compound. It undergoes regioselective Markovnikov addition reaction with terminal alkynes in the presence of palladium-1,2-bis(diphenylphosphino)ethane complex (catalyst). Ethyl phenylphosphinate is the photodecomposition product of Inezin (S-benzyl O-ethyl phenylphosphonothiolate) on the ultraviolet irradiation. It can be prepared by the reaction of phosphinic acid with ethyl chloroformate in the presence of pyridine. Its ethylation using ethyl trimethylsilyl phenylphosphonite or the corresponding trimethylstannyl ester has been described. Its free-radical addition to ethylene has been reported to proceed with the retention of configuration.
Alkalmazás
Ethyl phenylphosphinate may be used in the preparation of the following diethyl imidazol-2-yl-(amino) methylphosphonates and phosphinates:
- imidazol-2-yl-methyl(N-butylamino)phosphonate diethyl ester

The photodecomposition of Inezin (S-benzyl O-ethyl phenylphosphonothiolate) in n-hexane under the ultraviiolet irradiation was investigated by gas liquid chromatography, thin layer chromatography, mass spectrometry, and infrared spectroscopy. Two main steps of photodecomposition were observed at the initial stage of irradiation.

Palladium-1,2-bis(diphenylphosphino)ethane complex catalyses regioselective Markovnikov addition of ethyl phenylphosphinate to terminal alkynes in toluene, while the use of tri-tert-butylphosphine as the ligand or ethanol as the solvent leads to regioselectivity reversal.
