WebIn 2024, Schoenebeck demonstrated that novel organogermanes could provide a solution to the problem posed by unstable 2-pyridyl and polyfluoroaryl boronic acids in Suzuki reactions. 48 Key benefits identified in this work: arylgermanes have low toxicity, 49 were easily synthesised from triethylgermanium chloride using Grignard reagents, and ... WebBorinic and boronic acids and esters (BR n (OR) 3-n. Compounds of the type BR n (OR) 3-n are called borinic esters (n = 2), boronic esters (n = 1), and borates (n = 0). Boronic acids are used in Suzuki reaction. Trimethyl borate, which is debatably not an organoboron compound, is an intermediate in the production of sodium borohydride. d hewitt https://marbob.net
