Chapter 9.4, Problem 6P

Interpretation Introduction

a)

Interpretation:

The alkyne which can be used as a starting material to prepare the compound given by hydroboration-oxidation reaction is to be stated.

Concept introduction:

The hydroboration reaction takes place with syn stereochemistry and results in a non-Markovnikov addition of water to the triple bond in an alkyne. The resulting product has the hydroxyl group on the less highly substituted carbon which tautomerises to yield carbonyl compounds. Terminal alkynes give an aldehyde while non-terminal internal alkynes give a ketone.

To state:

The alkyne which can be used as a starting material to prepare the compound given by hydroboration-oxidation reaction.
