INTERMEDIATES IN THE LEUCKART REACTION OF BENZOPHENONE WITH FORMAMIDE

The isolation of benzhydrol and its ether in conjunction with N-formylbenzhydrylamine in the Leuckart reaction of benzophenone is reported; it is postulated that this alcohol is a possible intermediate in the reaction.

An expedient, efficient and solvent-free synthesis of T3P-mediated amidation of benzhydrols with poorly reactive N-nucleophiles under MW irradiation

An expedient, efficient, economical, environmentally benign, and solvent free amidation protocol of benzhydrols with less reactive nitrogen nucleophiles assisted by propylphosphonic anhydride (T3P) under microwave irradiation has been developed. The methodology has been deployed for a wide range of heterocycles and electron-withdrawing & electron-donating groups. The protocol resulted in good to excellent yields under the given conditions (26 examples, 68-93% yield).

Monoallylation and benzylation of dicarbonyl compounds with alcohols catalysed by a cationic cobalt(iii) compound

Monoallylation and monoalkylation of diketones and β-keto esters with allylic and benzylic alcohols catalysed by [Cp*Co(CH3CN)3][SbF6]2(I) are reported. The method does not require any additive and affords regioselective products. The mechanistic investigations were done byin situ1H NMR spectroscopy as well as control experiments. It has been shown that reactions proceedviaη3-allyl complex formation or ally ether intermediate. The alkylation takes placeviaonly ether intermediate. The resulting allylated and alkylated products have been used for the synthesis of eleven new trisubstituted pyrazoles and one pyrazolone.
