Eliminationreactions of enolsulphonates have been further studied. The enolsulphonates of p-anisolyl-, 2-furoyl-, and 2-thenoyl-malonic esters readily gave the corresponding propiolic acids on treatment with base, whereas the enolsulphonates of o-, m-, and p-nitrobenzoylmalonic esters gave negligible yields. The enolsulphonates of cyclopropylcarbonylmalonate gave cyclopropylpropiolic acid, while
