摘要
An efficient and green approach to the synthesis of 2,2'-arylmethylene bis(3-hydroxy-5,5-dimethylcyclohex-2-enone) using L-histidine as the catalyst is described. In addition, room temperature ionic liquid 1-butyl-3-methylimidazonium tetrafluoroborate [bmim] BF4 was used as green recyclable alternatives to volatile organic solvents for this condensation reaction. This green catalytic system can be recycled several times with no decreases in yields and reaction rates.
