Improved Procedure for the Large Scale Synthesis of 1,2,3,4,4a,9b-Hexahydrodibenzothiophene

摘要

1,2,3,4,4a,9b-Hexahydrodibenzothiophene (5) is an important intermediate in the hydrodesulfurization of dibenzothiophene. Hydrodesulfurization is the catalytic process by which sulfur is removed from petroleum feed stock by treatment with hydrogen.
