Chapter 7.9, Problem 7.6P

(a)

Interpretation Introduction

Interpretation:

1-Heptanol is synthesised using given synthetic scheme has to be shown.

Concept introduction:

The Lindlar catalyst is a deactivated hydrogenation catalyst that stops alkyne hydrogenation at the alkene stage, allowing conversion of alkynes to cis-alkenes. Hydroboration followed by an acid workup (instead of basic peroxide) also gives cis-alkenes from alkynes. Hydroboration–protonolysis is an alternative way to prepare a cis-alkene from an alkyne.

Hydroboration–protonolysis is an alternative way to prepare a cis-alkene from an alkyne.
