O-Directed hydrostannation of b-cyclopropyl propargyl alcohol 22 with stannanes and cat. Et3B in THF/H2O or PhMe/MeOH fails todeliver any detectable products of α-stannylvinyl cation capture. Instead only α-stannyl-β-cyclopropylvinyl radical intermediates canbe detected, which undergo fast H-atom abstraction and/or cyclopropane ring-opening as a result of eliminative β-scission.

FingerprintDive into the research topics of 'Fast ring-opening of an intermediary α-stannyl-β-cyclopropylvinyl radical does not support formation of an α-stannylvinyl cation in the O-directed free radical hydrostannation of dialkyl acetylenes'. Together they form a unique fingerprint.
