Abstract
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.
