the reaction of tertiary, secondary and benzylic alcohols with different nitriles in the presence of alumina-methanesulfonic acid (ama) as a new reagent affords the corresponding amides in good yields (table 1, 2). conversion of 2,6-bis(hydroxymethyl)-4-halo anisoles into corresponding diamides in the range of 68-76% yields (table 3) are also included in this paper.

an efficient one-pot oxidation/condensation tandem process has been developed for the synthesis of 2-substituted benzimidazole derivatives from benzylic alcohols and 1,2-phenylenediamine with use of urea-hydrogen peroxide/silica phosphoric acid  as a bifunctional catalyst. this method provides a rapid and efficient access to 2-substituted benzimidazoles.

An efficient method for molecular iodine catalyzed decarboxylative substitution of β-keto acids with benzylic alcohols under mild conditions has been described and valuable α-functionalized ketones were obtained in good to excellent yields.

An acid-catalysed Ritter reaction of chiral secondary benzylic alcohols enables diastereoselective access to chiral amides, which represent inter alia valuable intermediates for the synthesis of chiral 1,2-diamines and beta-amino acids.

Unsubstituted phthalocyanines of Co, Fe and Mn supported on zinc oxide nanoparticles were prepared and were well characterized with X-ray diffraction and scanning electron microscopy. The oxidation of alcohols with tert-butylhydroperoxide, in the presence of metallophthalocyanines supported on zinc oxide nanoparticles was investigated. These MPc/ZnO nanocomposites were effective catalysts for t...

Cu/TEMPO catalyst systems promote efficient aerobic oxidation of sterically unhindered primary alcohols and electronically activated substrates, but they show reduced reactivity with aliphatic and secondary alcohols. Here, we report a catalyst system, consisting of ((MeO)bpy)Cu(I)(OTf) and ABNO ((MeO)bpy = 4,4'-dimethoxy-2,2'-bipyridine; ABNO = 9-azabicyclo[3.3.1]nonane N-oxyl), that mediates a...

Organoboron compounds are useful in asymmetric synthesis. We have developed an efficient methodology for the highly enantioselective synthesis of tertiary boronic esters from the corresponding secondary benzylic alcohols. Further stereospecific transformations of the boronic ester moiety are described including the preparation of tertiary alcohols, C-tertiary amines and tertiary arylalkanes. Se...
