Hydrovinylation using Dendritic Catalysts in a CFMR

Application of a non-covalently functionalized dendrimer (see fig. 7) in a CFMR in the allylic amination of crotyl acetate and piperidine in dichloromethane (Koch MPF-60 NF membrane, molecular weight cut-off = 400 Da) (21). [Pg.84]

In a subsequent experiment, the larger dendritic catalyst 6b was used under optimized eonditions, whieh was expected to result in a slower loss of activity. The results (Fig. 9b) did not show much improvement, indicating that catalyst deactivation was still a major problem. Indeed the number of turnovers (catalytic reaction events) of catalyst 6b was only 260 in the continuous process compared with the value of 3 273 determined in the batch reaction experiment in contrast, the monomeric model compound showed a number of turnovers of 6 027. [Pg.85]
