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.(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
