Mixtures of sulfoxides with molecular solvents possess interesting physicochemical properties and may have applications in chemical synthesis. Hereby we confirm rationalize the previously reported excellent miscibility diethyl sulfoxide (DESO) methanol (MeOH). By performing a comprehensive potential energy surface investigation identified global minimum for each system significant number local ...

Rates and selectivities for the oxidation of various organosulfur compounds with tert-butyl hydroperoxide were measured on CoAPO-5 (APO = aluminophosphate; Co/P = 0.05), Co/H-Y (Co/Al = 0.15), and MoO(x)/Al2O3 (15 % wt MoO3). Rates increased with increasing electron density at the sulfur atom (methyl phenyl sulfide>diphenyl sulfide>4-methyldibenzothiophene>2,5-dimethyl thiophene). Rates (per me...

The relative reactivity of a series of nucleophiles that includes ethylene, sulfides, sulfoxides, amines, and phosphines toward dioxirane, dimethyldioxirane, carbonyloxide and dimethylcarbonyloxide has been U U Ž . U examined at the MP4r6-31G rrMP2r6-31G , QCISD T r6-31G rrMP2r631G , and B3-LYPr6-31G levels of theory. The barriers for the oxidations with Ž . dimethyldioxirane are higher up to 2...
