| Uses | Ethynyl trimethylsilane is used to produce new histone deacetylase inhibitors for the treatment of Freidreich ataxia. It also contributes to the preparation of conjugated polymers with an anthracene skeleton. Commonly used intermediates in asymmetric synthesis. silicon reagent Ethynyltrimethylsilane is used in the production of novel histone deacetylase inhibitors for the treatment of Freidreich holmium ataxia. it also aids in the preparation of conjugated polymers with sn anthra cene backbone. silicon protecting group, used to synthesize pyrazole, nickel-catalyzed and benzonitrile coupling reaction substrate by 1,3-bipolar cycloaddition of acetylene diazepines. |
| Silicone-based protective group | Trimethylsilyl acetylene is a kind of silicone-based protective group, also known as trimethylacetylsilane, trimethylsilylacetylene, trimethylacetylsilane, acetyltrimethyltrimethylsilane, It is a colorless and transparent liquid at room temperature, and pyrazole is synthesized by the 1,3-bipolar cycloaddition of acetylene diazo compounds, it is also a substrate for nickel-catalyzed and benzonitrile coupling reactions. |
