Brønsted acidic ionic liquid as an efficient and reusable catalyst for one-pot synthesis of 1-amidoalkyl 2-naphthols under solvent-free conditions

Multicomponent Reactions in Ionic Liquids

“…[23], [24] Hajipor et al ' 4 ] has been used previously as an efficient and reusable catalyst for nitration of aromatic compounds and esterification of various alcohols by different acids. [25]- [27] The acidic nature of BAILs has been exploited as catalysts for many other significant organic reactions, which proceed with excellent yields and selectivities and demonstrate the great potential of these ILs in catalytic technologies for chemical production. [23] Kotadia et al and Zhang independently reported the synthesis of similar 1-amidoalkylnaphthols using solid supported ionic liquids (SSILs).…”

K2FeZrP3O12 as an Efficient Catalyst for Friedel–Crafts Benzylation under Solvent-Free Conditions

“…Solid acid such as zeolite and clays, 5 sulfated zirconia, 6 nafion-silica, 7 alumina-supported niobia 8 and UDCaT-4 9 have been used for Friedel-Crafts alkylation. In continuation of our ongoing project for developing efficient solid acid, 10,11 we found that potassium iron zirconium phosphate (PIZP) can be used as an efficient and heterogeneous solid acid for Friedel-Crafts benzylation under mild conditions. PIZP catalyst was prepared by the reported sol-gel procedure that offers better control over surface, pore volume and pore size.…”
