Abstract

Abstract The 13 C NMR spectra of 28 enethiolizable β-thioxo esters and 6 enethiolizable β- thioxo thioloesters have been recorded in order to establish the tautomeric phenotypes of these compounds. All compounds investigated are essentially enethiolic. The carbonyl- conjugated (Z)-enethiol form is the exclusive or predominant tautomer of open-chain β- thioxo esters and thioloesters, thioacylmalonates and medium-sized 2- ...
