the difficult to handle and store zinc borohydride, zn(bh4)2, is stabilized by supporting it on polyvinylpyridine. this new mild, efficient, selective, and regenerable polymer supported borohydride reducing agent reduces a variety organic compounds such as, aldehydes, a-b-unsaturated carbonyl compounds, acid chlorides, epoxides, disulfides, as well as reductive acetylation of carbonyl compounds...

Chiral phase‐transfer catalyst brings insoluble ionic halogenating reagents into the solution and mediates enantioselective halogenations by forming highly ordered asymmetric environments through ion pairing and/or hydrogen‐bonding interactions with substrate reagent. Such approaches have been enormously successful in both nucleophilic electrophilic halogenations. In this review, remarkable exa...

a convenient, one-pot method for the synthesis of diazonium salt has been developed by the sequential diazotization of aromatic amines with nano2, polymer- supported periodic acid (ppia) and 2-naphthole under solvent-free conditions at room temperature. by using this method, several types of aromatic amine, containing electron-withdrawing and electron-donating groups, were rapidly converted to ...

the polymer supported hypochlorite ion is a facile selective oxidizing agent for the oxidation of various alcohols to aldehydes and ketones. similarly is successfully oxidizes various hantzsch type 1,4- dihydropyridines to corresponding pyridines.

Soluble polymers have been used as supports for reagent/catalyst immobilization and synthesis. Two polymers are commonly used in this context, linear polystyrene and poly(ethylene glycol). The complementary solubility properties of these polymers allow access to a wide range of chemistries. Parallel and combinatorial libraries of small molecules have been prepared using these polymers, and reag...
