, p. 1771 - 1772 (1994)
A refined verson of the Meyers' modification of the Ramberg-Baecklund reaction employing the reagent alumina-supported KOH-CBr2F2-ButOH allows α- and α'-hydrogen-bearing sulfones of various structural types to be converted into alkenes.
Synthesis, characterization, and optical response of dipolar and non-dipolar poly(phenylenevinylene) dendrimers

, p. 5664 - 5670 (2007/10/03)
New dipolar and non-dipolar poly(phenylenevinylene) dendrimers bearing electron-donating and electron-withdrawing groups have been efficiently synthesized using Heck and Horner-Wadsworth-Emmons reactions. The photoluminescence of these systems may be tuned in the blue zone by choosing the appropriate peripheral groups. Despite the meta-substitution pattern, large Stokes shifts can be observed when π-donor and π-acceptor groups are connected by a m-phenylenevinylene system.
A Horner-Wadsworth-Emmons approach to dipolar and non-dipolar poly(phenylenevinylene)dendrimers
Diez-Barra, Enrique,Garcia-Martinez, Joaquin C.,Rodriguez-Lopez, Julian
, p. 8181 - 8184 (2007/10/03)
The synthesis of first generation phenylenevinylene dendrimers is described. The Horner-Wadsworth-Emmons reaction is used for this purpose. The reported methodology permits the preparation of dipolar and non-dipolar structures. A second generation dendron bearing peripheral electron donor groups is also reported.
Magnetic Spin Exchange Interactions between Several Metal Centres in Paramagnetic Complexes with New Polynucleating Bridging Ligands
Amoroso, Angelo J.,Maher, John P.,McCleverty, Jon A.,Ward, Michael D.
, p. 1273 - 1276 (2007/10/02)
The polynucleating bridging ligands L1 and H3L2 were simply prepared via a Heck coupling of 4-vinylpyridine or 4-methoxystyrene with 1,3,5-tribromobenzene; in the trinuclear complexes of L1 and L2 with a paramagnetic Cl> moiety at each binding site the EPR spectra demonstrate that all three unpaired electrons are in 'fast exchange' between all three metal centres.
