We present a new type of elementoboration reaction, the thioboration of terminal alkynes. This method enables highly controllable regio-/stereo-/chemoselective - and -thioboration on demand, affording synthetically versatile and densely functionalized vinyl boron/vinyl sulfide derivatives in a straightforward manner without the need for a transition-metal catalyst.
