A microwave assisted synthesis methodology has been presented for the preparation of the bisferrocenoyl esters and thioesters. 1,1鈥?bis-ferrocenedicarboxylic acid was derivatized using direct 1H-benzotriazole/SOCl₂ methodology to prepare 1,1鈥?bis-(N-benzotriazolyl) ferrocenecarboxamide, 1, as a convenient tool for the functionalization of ferrocene ring. The starting material, 1, was reacted with alcohols and thiols in mild conditions to prepare bisferrocenoyl esters and thioesters in high purity and in moderate yields. The solid state structure of 2b has also been determined by X-ray crystallography. H-bond interactions and plane geometries between ring systems have been discussed.
