一般描述
(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.
应用
(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)ADT2,8-dipropyl-5,11-bis(triethylsilylethynyl)ADT
