Destroyer ochem quick question

[Jordwin]

I was just wondering if this reaction would produce 2 equivalents of answer B due to there being two borons. Is this correct?

Sorry, here it is.

Dichromate will reduce (I think...f***ing hate ox/redox terms) secondary alcohol to a ketone. Remember - chromate is strong, PCC is weak.

Ph3P signifies Wittig Reaction, which takes any carbonyl bond and creates an alkene with the attached group (in this case methyl). 2nd step product would be methyl cyclohexane.

Borohydride/THF signifies Anti-Markovnikov addition of OH, therefore OH is added to the primary carbon on the methyl group instead of the tertiary carbon on the ring.

Also don't think there'd be two products - the two borons in borohydride act as one entity...I think. Don't recall if that was ever marked on my orgo review sheet.

Yeah I believe you are right but no one cares because it's Ochem and balancing reactions don't typically matter. I think I remember chad saying BH3 could do the same thing.

Yeah, that's why I was wondering. I remembered him saying that. So no worries tho probably?

In Chad's videos...Chad The Man explains that BH3 can also be written as B2H6, but they mean the same thing, so no you wouldn't have 2 equivalents
