(TRIETHYLSILYL)ACETYLENE Chemical Properties,Uses,Production

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.
