Chemistry – A European Journal, Volume 31, Issue 70, December 12, 2025.Synthesis of tribenzothiepine S‐oxide was achieved chemo‐ and stereoselectively to give rise to stable exo vs. endo sulfoxide isomers displaying stereodependent photochemical behavior. Their light‐induced ring contraction, coupled to a concomitant extrusion of SO, was investigated in solution and in the solid state, en route to post‐processing ...

Study of a desulfurization process to convert dibenzothiophene to 2-hydroxybiphenyl by Rhodococcus rhodochrous NRRL (B-2149) [PDF]
, 2007 [Abstract] Actually, a great effort is being given to research on biodesulfurization processes, i.e., processes in which sulfur can be removed selectively from sulfur-compound moities without altering its British thermal unit.

Carbonylative Transformations of Aryl Sulfonium Salts
Chemistry–Methods, Volume 5, Issue 12, November 2025.Carbonyl derivatives are widely present in biologically active molecules, pharmaceuticals, natural products, and materials, and their synthesis has garnered much attention. Direct carbonylation of aromatic CH bonds is an effective tool for the synthesis of carbonyl compounds.
