Great blog Prof!
The 3rd problem set, 1st reaction. The Hydroboration oxidation. In the answer shouldn’t you show that it is a syn-addition?

In reply to Yo. The advantage of oxymercuration is that there are no carbocation rearrangements.

In reply to Ricardo. Glad you find it useful Ricardo!

what advantage does the oxymercuration reaction have over the other reaction for formation of alcohols that has the same regioselectivity?

I don’t know.

what are two methods of forming alkyl halides form alkenes that have opposite regioselectivity?
1.HBr, peroxide radical addition
2.HBr

using reactions we’ve learned before, how can the sequence alkane –>Br2. alkyl halide –>use NaOH. alkene —> epoxide .use mCPBA

using reactions we’ve learned before, how can the sequence alkane –> alkyl halide –> alkene –> alkane be accomplished?
1.Br2,HV

2.NaOH
3.H2,Pt,C

>>At 25th point, Iodohydrin formation, it should be Iodine. Chlorine is written.
>>Can Ag silver catalyst (instead of RO3H) be used to form epoxides from alkenes?
>>Oxidative cleavage of 2-Methlypropene with Hot, Acidic KMnO4 gives Propanone, carbon dioxide and water. The trick (see point no. 31) you mentioned above doesn’t apply here (C-H bonds are not oxidised to C-OH).

Thanks for the great website. It has helped me a lot.

In reply to Ethan. ChemDraw. You probably have access to it for free at your educational institution.

What program did you use to draw the molecules and make the concept map? I am trying to keep all the reactions I know straight!!

Thanks a lot for the chart, it beautifully collects all of these reactions in an easy to visualize way. Keep doing what you do!

This is an absolutely great resource as I try to recap and get these back in my head from Org 1 as we start synthesis in Org 2. Do you know of a website or etc. as a good drilling or practice resource? Thanks again for all your posts!!!
