ChemInform Abstract: A Liquid—Liquid Biphasic Homogeneous Organocatalytic Aldol Protocol Based on the Use of a Silica Gel Bound Multilayered Ionic Liquid Phase.

Elisa Montroni、Marco Lombardo、Arianna Quintavalla 等 6 位作者2012-10-11ChemInform

Abstract Key feature of the title protocol is the use of a cis‐ion‐tagged proline dissolved in a liquid film on a multilayered ionic liquid covalently bound to silica. The resulting catalytically active material is soaked in cyclohexanone and water to form a semi‐transparent gel which then reacts with the aldehyde.
