Conclusions
-
1.
The reaction of S-alkyl ethyl (phenyl)chlorothiophosphonites withβ-ketoalcohols in the presence of triethylamine leads to the formation of O-γ-ketoalkyl S-alkyl ethyl(phenyl)thiophosphonites.
-
2.
The O-γ-ketoalkyl S-alkyl ethyl(phenyl)thiophosphonites are inclined to isomerize to the S-alkyl (γ-ketoalkyl)ethyl (phenyl)thiophosphinates.
