The four constitutionally isomeric alcohols shown below can each be made selectively by one or both of hydroboration/oxidation or oxymercuration/demercuration of one or two constitutionally isomeric alkenes. For each of (a)-(d) write one or two alkenes (as indicated) that is/are appropriate starting materials, and for each alkene which of two reagent combinations is needed to produce the indicated alcohol. You can disregard stereochemistry in this problem, and focus just on regiochemistry. In other words, be sure the OH will become...

6. The alcohol below can be made from two different alkenes via a hydroboration/oxidation series, but one of the potential alkene starting materials isn't good because it produces 3 other isomers in addition to the compound below. Draw all 3 and indicate their relationship to the product below (i.e., enantiomers, diastereomers, etc.). OH 7. What is the product when cholesterol is subjected to hydroboration/oxidation conditions? 8. The compound below reacts differently under...

Identify the two diastereomeric hydroboration-oxidation products that can be formed from the following alkene by dragging the product pair to the product bin. Then suggest which product should be the major product or whether they will be formed in equal amounts by dragging the appropriate label to the bin under the products. Note: If one or more labels are incorrectly placed, a single red X will appear on the top left. 1) BH3, THF 2) H2O2, -OH Incorrect. o do.com...

13 SN1: Synthesis of tert-Butyl Chloride Alkyl halides can be prepared from their corresponding alcohols via an acid catalyzed substitution reaction. The mechanism of these acid catalyzed substitution reactions are labeled as Syl (substitution, nucleophilic, unimolecular) and S2 (substitution, nucleophilic, bimolecular). Tertiary alcohols follow the Snl route, primary alcohols follow the S2 route, and secondary alcohols can follow either path. Under acidic conditions, the mechanism (Figure 1) of the Sul reaction involves rapid protonation of the alcohol, followed by the...
