AMOOZADEH, Ali  e  NEMATI, Firouzeh. Solid silica-based sulphonic acid as an efficient green catalyst for the selective oxidation of sulphides to sulphoxides using NaCIO in aqueous media. S.Afr.j.chem. (Online) [online]. 2009, vol.62, pp. 44-46. ISSN 1996-840X.

A range of sulphides can be selectively oxidized to the corresponding sulphoxides in good yields using NaClO/silica sulphonic acid as an efficient and recyclable solid acid catalyst, in both water and 50/50 water/EtOH as solvents. The new method compares favourably with previous methods in the literature.

Palavras-chave : Silica sulphonic acid; heterogeneous catalyst; oxidation; sulphides; sulphoxides.
