The alternating ROMP assembly of trans-RuCl2((R)-5,5'-dinorimido-BINAP)(Py)(2) (5) and COE using RuCl2(CHPh)(PCy3)(2) (7) as the catalyst resulted in an extended, three-dimensional catalyst-organic framework. The catalyst-organic framework was converted to contain Noyori-type active sites that were recycled for 25 times at low catalyst loadings without loss in enantioselectivity or activity and without detectable Ru leaching.
