Covalent grafting of pyridine-2-methanol into kaolinite layers
(Elsevier, 2013)
A novel hybrid organic-clay material was prepared by grafting of pyridine-2-methanol in the interlayer space of kaolinite by using a kaolinite/methanol compound as an intermediate. A kaolinite/methanol compound was obtained ...
An efficient synthesis of benzimidazoles via a microwave technique and evaluation of their biological activities
(Springer Wien, 2013)
A simple and practical protocol was developed for the synthesis of benzimidazoles. the protocol uses iminoester hydrochloride which is very useful in the reaction with 4,5-dichloro-1,2-phenylenediamine under microwave ...
