afforded the ([2,2':5',2''-terthiophen]-3'-ylethynyl)trimethylsilane. Using a onepot reaction for the last step, the deprotection of the TMS-protected alkyne and its coupling with 4- bromo-2,2’-bipyridine was accomplished easily. A final 52% yield was achieved over 5 steps. Conclusion: The ligand 4-([2,2':5',2''-terthiophen]-3'-ylethynyl)-2,2'-bipyridine was prepared in a 52% yield, over 5 steps, improving
