Photoredox of Gem-Diborylalkenes: A Novel Reactivity Toward Diverse 1,1-Bisborylalkanes

The use of gem-bis-metalated-alkenes, i.e., vinyl gemdiboron-compound, as light-labile substrates is explored for the first time. The knowledge gained provided us with an in-depth understanding of the reactivity of novel radical intermediates of geminal-metalated ethane. This methodology can serve as the late-stage diversification of bioactive molecules and simple organic molecules in which it drives the synthesis of gemdiborylalkanes.
