Synthesis of Nucleophilic Adducts of Thiols (V). Addition of Thioglycolic Acid to $\omega,\;\omega$-Diacetylstyrene Derivatives

The addition reactions of thioglycolic acid to , -diacetylstyrene derivatives were investigated. , -Diacetylstyrene derivatives easily undergo addition reactions with thioglycolic acid to form s-(2, 2-diacetyl-1-phenylethyl)-thiogycolic acid, s-[2,2-diacetyl-1-(methyl) phenylethyl]-thioglycolic acid, s-[2,2-diacetyl-1-(p-methoxy) phenylethyl]-thioglycolic acid and s-[2,2-diacetyl-1-(p-chloro) phenylethyl]-thioglycolic acid, respectively. The structures of these compounds were identified by neutralization equivalent, UV, IR, and NMR spectral data.
