Abstract:The incorporation of two distinct boryl groups at the same carbon center in organic molecules has attracted growing research interest due to its potential for facilitating controlled, precise synthesis through stepwise dual carbon‐boron bond transformations. Here we report a method to access unsymmetrical 1,1‐diborylalkene (UDBA) stereoselectively via the reaction of readily available alkynes with a neutral sp2‐sp3 diboron reagent (NHC)BH2‐Bpin (NHC = N‐heterocyclic carbene). Attributing to the chemically easi… Show more
