Room-temperature desulfurization of dibenzothiophene mediated by [(i-Pr2PCH2)2NiH]2

Research was conducted to study the synthesis of an organometallic nickel complex which could activate the C-S bond of dibenzothiophenes. The desulfurization of dibenzothiophenes did not require a hydride, a proton, or a hydrogen atom source. Results indicated that the complex was able to mediate activation of both C-S bonds of dibenzothiophenes at room temperature, and produced structurally characterized organometallic compounds.
