In the first step, borane (BH3) adds to the double bond, transferring one of the hydrogen atoms to the carbon adjacent to the one that becomes bonded to the boron. This hydroboration is repeated two additional times, successively reacting each B–H bond so that three alkenes add to each BH3. The resulting trialkylborane is treated with hydrogen peroxide in the second step. This proc… Web10 nov. 2014 · Hydroboration Oxidation Alkene reaction mechanism broken down step by step to help you learn and understand the concepts, reagents, mechanism and reaction fo... easy sewing craft projectsWebWe start with an alkene and in the first step this is our hydroboration-oxidation step we're adding borene which is BH3 and tetrahydrofuran which is THF. Our second step is the oxidation where we add hydrogen peroxide and a source of hydroxide ions, and we can see what our product would be.
