Allenyl-1a,b and alkynyl-stannanes 2a-c are synthesized by reaction of the corresponding allenyl- and alkynyl-tributylstannanes with tin tetrachloride or dichlorodimethylstannane followed by a chemoselective reduction of the formed chlorostannanes with tributylstannane in the presence of duroquinone or galvinoxyl, a radical inhibitor.
