Green, Efficient and Reusable Bis(imidazolium) Ionic Liquids Promoted Pd-Catalyzed Aqueous Suzuki Reaction for Organic Functional Materials

Glucopyranoside-substituted asymmetric bis(imidazolium) ionic liquids were used to promote environmentally friendly, efficient and reusable Pd-catalyzed Suzuki reaction between arylboronic acids and 2-bromofluorene, 2,7-dibromo-9,9′-dialkylfluorene. Over 30 carbazole-based fluorene core potential organic functional materials were synthesized. In addition, recyclability of catalyst system was inspected on the Suzuki reaction observing nearly no loss in catalytic activity up to five cycles. Development of green, efficient and recycle glucopyranoside substituted bis(imidazolium) ILs promoted Pd-catalyzed aqueous Suzuki reaction for OFMs.
