Preparation and reactions of 1,1-di(phenylthio)cyclobutane derivatives from 1-(phenylthio)-1-cyclopropane carbinols
Kwon,Smith
, p. 2273 - 2285 (2007/10/02)
1-(Phenylthio)cyclopropylcarbinyl alcohols are converted to 2-alkyl-1,1-di(phenylthio)cyclobutane derivatives upon treatment with 48% HBr and ZnBr2. Heating with copper triflate and Hunig's base gave 2-alkyl-1-(phenylthio)cyclobutenes which wer
