Resumo

CHIKHALE, Rupesh V. et al. Poly (Ethylene Glycol)-Bound Sulphonic Acid as a Novel Catalyst for Synthesis of Benzoxazoles. S.Afr.j.chem. (Online) [online]. 2013, vol.66, pp.254-262. ISSN 1996-840X.

A highly efficient, simple and rapid method for the preparation of various 2-aminobenzoxazoles and other benzoxazole derivatives using a catalytic amount of poly (ethylene glycol)-bound sulphonic acid (PEG-SO3H) is described. PEG-SO3H is found to be economical and reusable catalyst with low catalytic loading. The percentage yield was found to be satisfactory, experimental set-up and purification of final products is facile and easy.

Palavras-chave : Poly (ethylene glycol)-bound sulphonic acid (PEG-SO3H); 2-aminobenzoxazole; benzoxazole derivatives.
