The gas-phase basicity and H/D exchange characteristics of the parent thiocarbonyl enolate anions
Abstract
The enethiolate anions corresponding to thioacetaldehye and thioacetone, synthesized via elimination reactions, undergo H/D exchange reactions, demonstrating the intermediacy of the thiocarbonyl tautomers, and proton transfer reactions, leading to ΔGacid0[CH3CHS]= 341 ± 3 kcal mol–1 and ΔGacid0[(CH3)2CS]= 344 ± 3 kcal mol–1(1 kcal = 4.184 KJ).
