(TRIETHYLSILYL)ACETYLENE Usage And Synthesis

Chemical Properties

Clear colorless to faintly yellow liquid

Uses

(Triethylsilyl)acetylene may be used in the synthesis of triethylsilylethynyl anthradithiophenes, such as :

• 2,8-dimethyl-5,11-bis(triethylsilylethynyl)ADT (ADT= anthradithiophene)
• 2,8-diethyl-5,11-bis(triethylsilylethynyl)ADT
• 2,8-dipropyl-5,11-bis(triethylsilylethynyl)ADT

General Description

(Triethylsilyl)acetylene, a bulky trialkylsilyl-protected alkyne, undergoes Cadiot-Chodkiewicz cross-coupling reaction with various bromoalkynes to yield synthetically useful unsymmetrical diynes. Rhodium-catalyzed dimerization of (triethylsilyl)acetylene has been reported.
