Abstract
By an example of butanethiol the addition of mercaptanes in the presence of bases to alkyl 3-furyl-3-(diethoxyphosphoryl)acrylic acids having methyl, methoxymethyl, or diethoxyphosphorylmethyl substituent in the furan ring was studied. It was shown that in the majority of cases alkyl 2-(butylthio)propionate was the main product, and 3-(butylthio)propionate was the minor one. Ethyl 3-(4-methylfur-3-yl)-3-(diethoxyphosphoryl) acrylate affords these two substances in equal quantities. In the case of ethyl 3-(4-methoxymethyl-5-methylfur-2-yl)-3-(diethoxyphosphoryl)acrylate only 3-(butylthio)propionate is formed.
