Unique silane modified perfluorosulfonic acids as versatile reagents for new solid acid catalysts

A new versatile reagent, a perfluorosulfonate/trisilanol [(OH) 3 Si(CH 2 ) 3 (CF 2 ) 2 O(CF 2 ) 2 SO 3 - M + ], is synthesized and a series of surface bound strong solid acid catalysts developed which are active for catalyzing a range of reactions, for example alkene isomerization, alkylations and acylations.
