Grubbs Heterogeneous

For the cross-metathesis of functionalised alkenes the ill-defined classical catalyst systems currently offer very few advantages (cost and heterogeneous catalysis) over the more functional group tolerant Schrock and Grubbs alkylidene... [Pg.188]

HETEROGENATION OF A SHIFF BASE SUBSTITUTED GRUBBS CATALYST AND A Ru-DIMER TO PERFORM ROMP REACTIONS... [Pg.451]

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]
