Polystyrene supported Al(OTf)3: A stable, efficient, selective, and reusable catalyst for sulfonylation of arenes with sulfonic acids

Cross-linked polystyrene supported aluminium triflate (Ps-Al(OTf) 3) was found to be an efficient and chemoselective heterogeneous Lewis acid catalyst for the direct conversion of arenes to sulfones using sulfonic acids as sulfonylating agents. The solid acid catalyst is stable (as a bench top catalyst) and can be easily recovered and reused without appreciable change in its efficiency.

METAL-ASSISTED REACTIONS-13. RAPID, SELECTIVE REDUCTIVE CLEAVAGE OF PHENOLIC HYDROXYL GROUPS BY CATALYTIC TRANSFER METHODS

Previous work has shown that, after converting phenols into suitable phenolic ethers, the aromatic C-O bond of the original phenol can be reductively cleaved heterogeneously to give a C-H bond through the use of molecular hydrogen or hydrogen donors together with a transition metal catalyst.The present work provides a method for selectively replacing a phenolic OH group by H in just a few minutes, compared with the 2 to 4 hr required previously using a hydrogen donor and the several hours under pressure required for molecular hydrogen.Various kinds of groups are suitable for preparing the required phenolic ethers from phenols, but the best ones are strongly electronwithdrawing heteroaromatic entities.Solvent appears to play an important role in this heterogeneous reaction, the mechanism of which is discussed.
