The invention relates to optical devices; especially intraocular lens made from high refractive index polymers produced from hydroxyalkyl acrylates and methacrylates containing aromatic groups and carbonyl groups. The invention also relates to the starting monomers, the polymers produced; the application of the same for the manufacture of optical devices and the products derived therefrom.

Oxidation of (11Z)-1′,2′-didehydrostemofoline with DIB/TBHP/Mg(OAc)2·4H2O resulted in oxidative cleavage of the C-11-C-12 double bond instead of the desired allylic oxidation of the 1-butenyl side chain. Stemofoline gave a similar result. The oxidation of more simple terminal alkenes was regioselective and gave vinyl ketones while allyl and benzyl ethers gave acrylate and benzoate esters, respectively. Allyl and benzyl ethers could be chemoselectively oxidized in the presence of a terminal alkene or benzyl group. Oxidation of an internal alkene was poorly regioselective, in contrast to the oxidation of 1-substituted cyclohexenes.
