Abstract

Dipyridyl-substituted heterocycles such as 2, 5-di (4-pyridyl) thiophene 3, 2, 5-di (4-pyridyl) furan 4, 2, 5-di (4-pyridyl) thieno [3, 2-b] thiophene 7, 1, 4-di (4-pyridyl) benzene 6, 2, 5-di (2- pyridyl) thiophene 8, and 2, 5-di (3-pyridyl) thiophene 9 have been efficiently synthesized by a simple one-pot procedure through the palladium-mediated cross-coupling reaction between (trimethylstannyl) pyridines and dibromo-substituted heteroaromatics. The ...
