Synthesis and Reactivity of Diethyl (Methylthio)(trimethylsilyl)methylphosphonate

The title compound is obtained in 80percent yield by silylation of the lithium salt of diethyl 1-methylthiomethylphosphonate.Other approaches involving sulfenylation of diethyl 1-trimethylsilylmethylphosphonate or the Arbuzov reaction of triethyl phosphite with bromo(methylthio)(trimethylsilyl)methane are less efficient.Aldehydes react with the lithium salt of diethyl (methylthio)(trimethylsilyl)methylphosphonate to give the corresponding 1-methylthioethenylphosphonates in good yields (60-85percent) while the reaction with ketones is more complex and Peterson reaction products are formed in very low yields.Methylation, silylation, sulfenylation, and oxidation of the title compound are also described.

THE USE OF PHOSPHONODITHIOFORMATES FOR THE SYNTHESIS OF KETENE DITHIOACETALS

Phosphonodithioformates 1 undergo thiophilic addition with both organolithium and Grignard reagents to give metallated dithioacetals of formyl-phosphonates 2, available for protonation, alkylation or use in Wittig-Horner reactions.Oxidation of 1 by meta-c

ZUR SYNTHESE VON BIS-ALKLYLMERCAPTO-METHANPHOSPHONSAEUREDIALKYLESTERN

To find a simple and reproducible synthesis of bis-alkylmercaptomethane phosphonates 1 several methods had been examined.The reaction of chloro-dialkylmercaptomethanes 3 with trialkylphosphite (Method A) and the reaction of diethylmethanphosphonate 8 with mercaptanes (Method F) proved to be the best methods.
