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. |
