Brpnsted acids super

The two following examples incorporate the fluorous super Brpnsted acid catalyst 13 for the acetalization of benzaldehyde with 1,3-propanediol and for the... [Pg.89]

Mukaiyama aldol reaction of an enol silyl ether with benzaldehyde (Scheme 17)7 These reactions were conducted in a neat organic solvent, and the catalyst was precipitated after cooling the reaction mixture to room temperature, hence permitting its easy recovery. The same group also reported on the use of a polystyrene-bounded super Brpnsted acid catalyst in a flow system. ... [Pg.90]

Once highly acidic Brpnsted acids are in hand, we can also use them as en effective Lewis acid catalysts for various organic transformations. This is simply because the metal attached to such a super conjugate base makes the metal site very... [Pg.326]
