Stupid question, but does (1) B2H6, THF (2) H2O2, OH-, just turn an alkene into a primary alcohol?

Err......no? It adds OH, H in a anti-markov fashion 🙂

Shiznit, I forgot. Thanks bud. So does that mean B2H6 and BH3 react the same way?

it can if the alkene is terminal, ya it is hydroboration

its a dimer of borane...not sure why it is a dimer though

unless in solution its normally a dimer and the way we see it normally written is for simplicity?

I was curious b/c I was doing some problems in Organic Odyssey and I saw the rxn conditions and it looked sooo familiar but I had no idea what it did.👎
