The reaction proceeds in a short time period to afford moderate to excellent yield of products. The ionic liquid was recycled and reused for multiple time significantly, without a change in its catalytic efficiency.  UR - https://www.ajgreenchem.com/article_100332.html L1 - https://www.ajgreenchem.com/article_100332_b414068f741fe2863faab92417214f25.pdf ER -
