A new reductive protocol of desulfurization was developed to desulfurate benzothiophene with KBH_(4) as reductant.Experimentally,the appropriate masses of CoCl_(2)·6H_2O and KBH_(4) were 0.50 g and(0.40 g),(respectively);the volume of CH_(3)OH was 20 mL,and the sulfur was reduced from 1.420×10~(-3) g/g to(1.75×)10~(-4) g/g,the desulfurization percentage was 88%;the reaction time was 20 min;and temperature should be controled under 15 ℃;the sulfur obtained by desulfurating benzothiophene was retained in(active)...

A new reductive protocol of desulfurization was developed to desulfurate benzothiophene with KBH_(4) as reductant.Experimentally,the appropriate masses of CoCl_(2)·6H_2O and KBH_(4) were 0.50 g and(0.40 g),(respectively);the volume of CH_(3)OH was 20 mL,and the sulfur was reduced from 1.420×10~(-3) g/g to(1.75×)10~(-4) g/g,the desulfurization percentage was 88%;the reaction time was 20 min;and temperature should be controled under 15 ℃;the sulfur obtained by desulfurating benzothiophene was retained in(active) cobalt boride formed during the reaction.The proposed mechanism is that the(reduction) reaction occurred between CoCl_(2)·6H_2O and the reductant in protic solvent,then black cobalt boride and H_(2) were formed;the hydrogenation desulfurization mechanism was deduced according the product distribution,and the reduction of benzothiophene was carried out through both the hydrogenation and direct hydrogenolysis routes;the substantive nascent hydrogen was absorbed and(activated) on the surface of the active solid,and was further transformed into(transient) intermediates,which attack the unsaturated bonds of benzothiophene and then led to the cleavage of C—S or C—C bond.
