Reaction of ethynylcyclopentanol with trifluoromethylsulfenyl chloride

Based on the mass spectral fragmentation behavior of the reaction products, the free radical reaction of I-ethynyl-l-cyclopentanol (1) with trifluorom ethylsulfenyl chloride (2) has been found to furnish 13 compounds formed fr om addition and elimination reactions. Two compounds are noteworthy in that one does not have the side chain, while the other carries an extended 'tri -ynyl' side chain. This paper presents the mechanism of formation of the va rious compounds and their GC-MS characterization. (C) 1999 Elsevier Science S.A. All rights reserved.
