Cyclodextrins or Calixarenes: What is the Best Mass Transfer Promoter for Suzuki Cross-Coupling Reactions in Water?

Cyclodextrins or calixarenes possessing extended hydrophobic host cavities and surface‐active properties were found to be very efficient as mass transfer promoters for the palladium‐mediated Suzuki cross‐coupling reaction of 1‐iodo‐4‐phenylbenzene and phenylboronic acid in aqueous medium. The cross‐...

Description
Summary:Cyclodextrins or calixarenes possessing extended hydrophobic host cavities and surface‐active properties were found to be very efficient as mass transfer promoters for the palladium‐mediated Suzuki cross‐coupling reaction of 1‐iodo‐4‐phenylbenzene and phenylboronic acid in aqueous medium. The cross‐coupling rates were up to 92 times higher than those obtained without addition of any compound.
