  Deep Hydrodesulfurization in Homogeneous Solution:  Access to a Transition-Metal Insertion Complex of 4,6-Dimethyldibenzothiophene

  摘要：

  Alkylated dibenzothiophenes are among the most difficult compounds to desulfurize in the hydroprocessing of crude oil, and information leading to their efficient removal is of tremendous value. Homogeneous nickel and platinum complexes were found to desulfurize alkylated dibenzothiophenes in the solution phase proceeding through well-characterized transition-metal insertion complexes.

  sulfur-free biphenyls via cross-coupling reactions. However, the mechanistic details involved in the process remained unknown. In this report the reactivity of [(dippe)Pt(μ-H)]2 with DBTO2 turned out to be catalytically less efficient compared with [(dippe)Ni(μ-H)]2, but the first allowed the isolation and full characterization of several reaction intermediates, such as [(dippe)Pt(κ2-C,S-DBTO2)]. It
