Poly(4-vinylpyridine)-supported dual acidic ionic liquid: A novel heterogeneous catalyst for the synthesis of β-Acetamido ketones

Article abstract of DOI:10.1080/15533174.2013.768647

Asupported dual acidic ionic liquid catalystwas easily prepared from its startingmaterials and used as an environmentally friendly heterogeneous catalytic system for the synthesis of β-acetamido ketones from the four-component condensation of an aromatic aldehyde with acetophenone, acetyl chloride, and acetonitrile at room temperature. This catalyst was also applied as an efficient catalyst for the synthesis of α-aminophosphonates. The catalyst favorably combines the properties of ionic liquids and advantages of solid supports and is recoverable without loss in its catalytic activity. Copyright Taylor & Francis Group, LLC.
