Synthesis of polymer supported catalyst

METAL CATALYSED CARBON-CARBON BOND-FORMING REACTIONS 

The loading of the catalyst can be determined by comparison of the relative integration of the 8 16.67 (Ru alkylidene) and 7.99 (benzoate) ppm signals. A 1 60 ratio indicates quantitative loading of the catalyst. Typical catalyst loadings using this procedure are between 0.08 and 0.10 mmolg  

Note Due to overlapping and very broad signals some of the highfield signal integrals are approximate, but nevertheless consistent between polymer batches. 

2 RING-CLOSING METATHESIS OF AN ACYCLIC DIENE AND SUBSEQUENT CATALYST RECOVERY/REUSE 

Alternatively addition of cold n-hexane or u-hexanc-diethyl ether (1 1) gives complete precipitation of the catalyst as a light green solid. The product can then be separated by a filtration/evaporation sequence.
