General description

2-Methyl-2-propanethiol undergoes ring opening nucleophilic reaction with 3-isothiazolones and reaction kinetics studies suggested reaction was second order in thiol and third order overall.

Application

2-Methyl-2-propanethiol was used in reaction of 2-methyl-2-propanethiol on Mo(110) using temperature programmed reaction, high resolution electron enegy loss and X-ray photoelectron spectroscopies. It was used in the synthesis of chain-transfer agents for reversible addition-fragmentation chain-transfer copolymerization of vinylidene chloride and methyl acrylate.
