Microporous and mesoporous molecular sieves for alkylation of toluene with olefins

Assembling of H5PW10V2O40/MCM-48 and studying its superior catalytic performance in the synthesis of 14-aryl-14-H-dibenzo[a, j]xanthenes

“…In order to overcome these common drawbacks, considerable efforts have been achieved to the development of heterogeneously catalysed organic reactions using solid acid catalysts such as zeolites, 19 clays, 20 and ion exchange resins. 21 In continuation of our previous works to develop non-hazardous and eco-friendly synthetic methodologies, [22][23][24][25] here we wish to report a highly versatile, eco-friendly, and efficient one pot heterogeneous protocol for the synthesis of aryl-14-H-dibenzo [a,j]xanthene derivatives from condensation of aldehydes and 2naphthol catalysed by a catalytic amount of heterogenized H 5 PW 10 V 2 O 40 /MCM-48 under solvent-free condition (scheme 1).…”
