Newly developed sulfonyl chloride-based regioselective chlorothiolation of alkenes has been disclosed; the reaction is compatible with a variety of functional groups and can be scaled up to the gram scale with no loss in yield. The employment of readily a

Reactions of unsaturated compounds with the PhSOEt-SOHal2 and PhSOEt-Me3SiHal systems (Hal = Cl or Br) were proposed as a new route to haloalkyl phenyl sulfides. With acyclic and mono- and bicyclic alkenes and dienes as examples, the

A variety of trans-β-substituted cyclic alcohols were stereoselectively chlorinated to either the corresponding cis-chloride or trans-chloride (inversion or retention of configuration) with good to excellent yields; the stereochemical outcome is determined by the size of the ring and the nature of the β-substituents, especially the electronegativity of the substituted atom.

A novel general synthetic route to tetraaryltetrabenzoporphyrins (Ar 4TBP) with various peripheral functional groups is developed. The procedure includes (i) Barton-Zard condensation of 1-nitro- or 1-phenylsulfonylcyclohexenes with isocyanoacet
A conjugate addition/sulfoxide elimination route to allylic difluorophosphonates

, p. 9085 - 9088 (2007/10/03)
Cerium-mediated conjugate additions of (diethoxyphosphinoyl) difluoromethyllithium to cyclic vinyl sulfoxides proceeded smoothly; thermal sulfoxide elimination afforded the products of formal vinylation, attaching the difluoromethylenephosphonato group to an alkenyl carbon atom. With acyclic vinyl sulfoxides, the addition occurred in moderate to poor yield. Addition failed completely in the absence of cerium(III) chloride, and was facilitated by an excess of the reagent.
SYNTHESIS OF β-FLUOROALKYL PHENYL (OR METHYL) THIOETHERS BY SULFUR-ASSISTED HALOGEN EXCHANGE WITH TRIETHYLAMINE TRIS-HYDROFLUORIDE

The exchange of chlorine in β-chloroalkyl phenyl (or methyl) thioethers by fluorine, with anchimeric assistance of sulfur, is very easily realized with the almost neutral fluorinating reagent, Et3N*3HF.The 'one-pot' reactions of alkenes with sulfenyl chlo
