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.
Pushing back the limits of hydrosilylation: Unprecedented catalytic reduction of organic ureas to formamidines
