General description
(tert-Butyldimethylsilyl)acetylene readily undergoes cross-dimerization reaction with various internal phenyl acetylenes in the presence of rhodium dimers and bidentate phosphine ligands to afford enynes.
(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.
Application
(tert-Butyldimethylsilyl)acetylene may be used in the synthesis of β-alkynylketone and β-alkynyl aldehydes.
