However, styrene and cyclohexene gave complex product mixtures, and 1-octene did not react under the same reaction conditions. Thus, the activity of this catalyst is intrinsically low. Jacobs and co-workers [159,160] applied Veturello s catalyst [PO WCKOj ]3- (tethered on a commercial nitrate-form resin with alkylammonium cations) to the epoxidation of allylic alcohols and terpenes. The regio- and diastereoselectivity of the parent homogeneous catalysts were preserved in the supported catalyst. For bulky alkenes, the reactivity of the POM catalyst was superior to that of Ti-based catalysts with large pore sizes such as Ti-p and Ti-MCM-48. The catalytic activity of the recycled catalyst was completely maintained after several cycles and the filtrate was catalytically inactive, indicating that the observed catalysis is truly heterogeneous in nature. 

Rates, Equilibria. Figure 2 illustrates results from the three methods of heterophase esterifrcation where linoleic acid is grafted to equal equivalents of the pendant carbinol groups in poly(styrene-co-allyl alcohol), PSAA-1. The methods include esterifications conduct in w/o microemulsion catalyzed by DBS A, in dispersion catalyzed by an acidic cation exchange resin and, finally, in a w/o emulsion catdyzed either by DBSA with water as an aqueous phase or by NaDBSA with 7.4N H2SO4 as an aqueous phase. In all runs about 46 wt % toluene was present as a...
