Optically transparent, high refractive index hydrogels and intraocular lenses fabricated therefrom. The preferred hydrogels have a refractive index of 1.45 or above and a water content of approximately 5 to 30 percent by weight.
Mechanistic studies concerning the use of 1,10-phenanthroline derivatives as palladium ligands in the Heck reaction are described. The work is focused on the steering factors for the coordination of unsaturated systems onto palladium(0) and palladium(II) complexes.
