Abstract:As an indispensable part of click chemistry, thiol-yne reactions are of great importance in organic and material synthesis. Nevertheless, efficient strategies for the addition of thiols onto internal alkynes with excellent regio- and stereocontrol are still scarce. Here we report the regio- and stereospecific hydrothiolation of electron-rich thioalkynes facilitated by organic base additive, which could proceed exceedingly fast under ambient atmosphere and room temperature, affording beta trans addition product… Show more
