Cross-linked poly(vinylpyrrolidone) (PVP) is a heterogeneous and polymeric support that has been widely used in the preparation of numerous reagents and catalysts because of its commercial availability, stability, reasonable high loading capacity, good physicochemical structure and facile functionalization. Beside various applications in industry such as stabilizer, sugar coating and film coating , this polymer can be an attractive support to immobilize mineral acids because of the basic nature of its pyridyl group. Therefore, recent applications of poly(vinylpyrrolidone) as a reagent support have been extensively investigated. In this spotlight we have a brief review on the applications of the modified poly(vinylpyrrolidone) in the promotion of some of the important organic transformations. پرونده مقاله
