Abstract

Photolysis of a hexane solution of ferrocenylacetylene and sulfur powder in presence of Cr(CO) 6 resulted in the formation of 2,6-diferrocenyldithiine and 2,5-diferrocenylthiophene. Similar reactions with Mo(CO) 6 or W(CO) 6 gave only the thiophene derivative. Formation of ferrocenyl-substituted thioketone complexes was observed in the reaction of ferrocenylacetylene with water and sulfur, in presence of W(CO) 6 . Use of D 2 O confirmed water as source of protons for the conversion of acetylenic CH to CH 3 .
