Tms Acetylene Chemical Properties,Uses,Production

Description

Tms Acetylene also called Trimethylsilylacetylene, is a versatile two carbon building block of considerable utility. Unlike acetylene itself, which is a gas at room temperature and potentially dangerous, this mono protected synthon is an easily handled liquid. In many instances introduction of the ethynyl group is facilitated by the use of TMS-acetylene. It can be used in many types of synthetic procedures without the need for specialized equipment.

Uses

Tms Acetylene is an extremely useful and "potentially nucleophilic" two carbon bifunctional equivalent synthon . It offers a significant advantage over acetylene gas, which is dangerous and difficult to use.
