Webbchap 9. Alkynes can be prepared by the elimination of HX from alkyl halides in much the same manner as alkenes (Section 8.1). Treatment of a 1,2-dihaloalkane (a vicinal dihalide) with an excess amount of a strong base such as KOH or NaNH2 results in a twofold elimination of HX and formation of an alkyne. As with the elimination of HX to form an ... WebbIt turns out BuCl has a convenient boiling point. Some pharma process groups opt to use n-hexyl lithium in large scale manufacturing - it is more expensive than BuLi but it has slightly lower tendency to self-ignite when spilled, and the main byproduct (hexane) is not gas. (Having a reaction mix saturated with butane - which boils off at room ... direct scattering problem
