Nanoporous TiO2 containing an ionic liquid bridge as an efficient and reusable catalyst for the synthesis of: N, N ′-diarylformamidines, benzoxazoles, benzothiazoles and benzimidazoles

In this work, a green and efficient procedure is reported for the preparation of N,N'-diarylformamidines, benzoxazoles, benzothiazoles, and benzimidazoles using nanoporous TiO2 containing an ionic liquid bridge. This reagent is prepared via the modification of nanoporous TiO2 with bis-3-(trimethoxysilylpropyl)-ammonium hydrogen sulfate (TiO2-[bip]-NH2+ HSO4-). The procedure gave the products in excellent yields in very short reaction times under solvent-free conditions. The reusability of the catalyst is the other important feature of the reported method.

An efficient method for the synthesis of formamidine and formamide derivatives promoted by sulfonated rice husk ash (RHA-SO3H)

A mild, simple and efficient method has been developed for the promotion of the preparation of N,N′-diphenylformamidines from various aromatic amines and ethyl orthoformate using sulfonated rice husk ash (RHA-SO3H) solid acid catalyst. This reagent has also been used for the N-formylation of a variety of amines using formic acid under solvent-free conditions. The procedures gave the products in very short reaction times and good-to-high yields. Also this catalyst can be reused for five times without loss of its catalytic activity.

Biomimetic approach for the synthesis of N,N′-diarylsubstituted formamidines catalyzed by β-cyclodextrin in water

An environmentally benign and highly efficient biomimetic approach for the synthesis of N,N′-diarylsubstituted formamidines in water catalyzed β-cyclodextrin is described under neutral condition with quantitative yields of products. β-Cyclodextrin has bee
