| | (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. |
