Abstract

These compounds represent hydride functionalities such as those proposed to exist on HDS catalyst surfaces (7-9). The neutral adduct Mn (CO) j (n-thiophene* H), 2, was formed. Adduct 2 reacted with strong acids such as HCl [a model for acidic surface SH sites (10, 21)] to give complex 3 with a 2, 3-dihydrothiophene (2, 3-DHT) ligand. Based on these model studies, 2, 3-DHT was proposed (6) as a possible intermediate for thiophene HDS, in ...
