TERT-BUTYLDIMETHYLSILYLACETYLENE Usage And Synthesis
Chemical PropertiesClear colorless liquid
Usestert-Butyldimethylsilylacetylene may be used in the synthesis of β-alkynylketone and β-alkynyl aldehydes. It participates in Cadiot-Chodkiewicz cross-coupling reaction with various bromoalkynes to afford synthetically useful unsymmetrical diynes.
General Description(tert-Butyldimethylsilyl)acetylene is a bulky trialkylsilyl-protected alkyne. It participates in Cadiot-Chodkiewicz cross-coupling reaction with various bromoalkynes to afford synthetically useful unsymmetrical diynes.
