1,1-Diborylalkanes RCH2CH(Bpin)2 were prepared by double borylation of α-alkynes catalyzed by 9-borabicyclononane via transborylation pathway. Olefin hydroboration reactions provide efficient access to synthetically versatile and easily handled organoboronic esters. In this study, we demonstrate that the com. available organoborane reagent 9-borabicyclo[3.3.1]nonane (H-B-9-BBN) can serve as a catalyst for the sequential double hydroboration of alkynes using pinacolborane (HBpin). This strategy, which is effective for a wide range of terminal alkynes, is predicated upon a key C(sp3)-B/B-H transborylation reaction. Transition-state thermodn. parameters and 10-boron-isotopic labeling experiments are indicative of a σ-bond metathesis exchange pathway. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Name: 4-Benzyloxyphenol).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Name: 4-Benzyloxyphenol
