“…However, because the iron phosphonate-containing polymers were more active, they gave mixtures of products with respect to hydrogenation and isomerization products. It should be noted that these researchers also employed supported palladium, nickel, and cobalt complexes in similar hydrogenation/isomerization experiments, with the former in conjunction with oxygenbased coordination groups, 787 while the latter two were with phosphorus groups (phosphinate and phosphonate) as the coordinating ligands on the polymeric supports. 788 5.6.3.…”
