An efficient and simple method is introduced for the selective removal of methyl group from poly aryl-methyl ethers, in some important derivatives of benzophenones, xanthones, anthraquinones, aryl esters, benzamides and nitroanisoles with BeCl2.
Photochromic naphthopyran compounds
-
, (2008/06/13)
Described are novel reversible photochromic naphthopyran compounds having at least one ortho substituted phenyl group at the 3-position of the pyran ring. Also described are organic host materials that contain or that are coated with such compounds. Articles such as ophthalmic lenses or other plastic transparencies that incorporate the novel naphthopyran compounds or combinations thereof with complementary photochromic compounds, e.g., spiro(indolino)-oxazine type compounds, are also described.
