alkoxide extrusion followed by dimerization or oxidation. This route also justifies the reactivity of alkenyl and alkynyl alkoxy Fischercarbenecomplexes toward other boron or aluminum hydrides. Finally, when a bulky reagent such as K-Selectride is employed, the 1,2-hydride addition is disfavored and only products derived from the reduction of the C−C multiple bonds are obtained.
