WebAug 12, 2024 · This work further investigated [Cu 2 (BAc) 4 (QX) 2] catalysed oxidation of dibenzothiophene (DBT) followed by the adsorption of the resulting dibenzothiophene sulfoxide (DBTO) over [Zn(TDPA) 2 (TMPy) 2] n. WebThen, the oxygen bonded to the catalyst is transferred to the S of dibenzothiophene (DBT) and sulfoxide is produced. By continuing this process, sulfoxide is converted into sulfone (Fig. S1).
WebFeb 1, 2010 · In addition there have been very few examples of the desulfurization of dibenzothiophene sulfoxide (3) [17,18], and dibenzothiophene sulfone (4) [10,19,20,21] as S-oxidized derivatives of this ring system. In fact, both lithium and sodium have been used to effect sulfur extrusions from dibenzothiophene. However, in both cases low … WebDibenzothiophene is prepared by the reaction of biphenyl with sulfur dichloride in the presence of aluminium chloride. Reduction with lithium results in scission of one C-S bond. With butyllithium, this heterocycle undergoes stepwise lithiation at the 4-position. S-oxidation with peroxides gives the sulfoxide.
