Metathesis The first successful use of ROMP-based monolithic media for heterogeneous catalysis was accomplished by employing these supports as carriers for the Grubbs ruthenium initiator based on NHC Ugands [135, 136]. In order to generate sufficient porosity, monoliths with a suitable microporosity (40%) and micro-globule diameter (1.5 0.5 pm) were synthesized. Consecutive in situ derivatization was successfully accompUshed using a mixture of NBE and a polymerizable NHC precursor (Scheme 11.12) [23, 98,137-139]. [Pg.270]

It is worth mentioning that the TONs obtained with these two supported versions exceeded all published data on TONs of supported well-defined metathesis catalysts at that time. Equally important, the contamination of the products with mthenium was (at that time) unprecedented low, that is, 1.8 ppm. The same group also reported on an extension of this work by immobilizing 1,3-dimesityltetrahydropyrimidin-2-ylidene-based on ROMP-derived monolithic supports. [Pg.625]
