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
Benzoporphyrins: Selective Co-sensitization in Dye-Sensitized Solar Cells
Lodermeyer, Fabian,Costa, Rubén D.,Malig, Jenny,Jux, Norbert,Guldi, Dirk M.

A novel class of dyes, namely benzoporphyrins, was synthesized and implemented into dye-sensitized solar cells. They feature complementary absorptions compared to N719, which renders them promising candidates for co-sensitization in DSSCs. Notably, metallated benzoporphyrins reveal a TiO2-nanoparticle attachment that is size and aggregation dependent. Therefore, unproductive energy-transfer events between the selectively attached dyes can be prevented. In light of the latter, an efficiency improvement of 39 % has been achieved upon selective adsorption of benzoporphyrins and N719 onto different layers of TiO2 photoelectrode.

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
Highly stereoselective chlorination of β-substituted cyclic alcohols using PPh3-NCS: Factors that control the stereoselectivity

, p. 867 - 869 (2007/10/03)
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.

Finikova, Olga S.,Cheprakov, Andrei V.,Beletskaya, Irina P.,Carroll, Patrick J.,Vinogradov, Sergei A.
, p. 522 - 535 (2007/10/03)
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
Blades, Kevin,Percy, Jonathan M.
, 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.
