Indium(iii) catalysed regio- and stereoselective hydrothiolation of bromoalkynes†
Abstract
The first example of metal catalysed hydrothiolation of bromoalkynes has been demonstrated. Indium(III) trifluoromethanesulfonate was reported as the first catalyst which can catalyse the addition of thiols to bromoalkynes with absolute selectivity to generate (Z)-β-bromo vinyl sulfides in good yields.
