This invention relates to a method of making in high yield light absorber compounds which are (2-cyano-3,3-diphenylacryloxy) alkylene acrylic acid esters having the formula: [Figure] where (Ar)1 and (Ar)2 are aromatic carbocyclic nuclei of the benzene and naphthalene series and are independently sel
This invention relates to a method of making in high yield light absorber compounds which are (2-cyano-3,3-diphenylacryloxy) alkylene acrylic acid esters having the formula: [Figure] where (Ar)1 and (Ar)2 are aromatic carbocyclic nuclei of the benzene and naphthalene series and are independently selected from phenyl or phenyl substituted with alkyl, halo, alkoxy, carboxy, carbalkoxy, cyano, acetyl, benzoyl, phenyl, alkyl phenyl, phenoxy phenyl, alkyl substituted phenoxy, or alkoxy phenyl substituted phenyl, and naphthyl; X is alkylene, C2-C17, unsubstituted or substituted with halo, cyano, alkyl, alkoxy, alkoxyalkyl, or alkoxyalkyleneoxy, C1-C6; and Y is copolymerizable radical selected from acryloyl, alkylacryloyl, acryloxyalkyl, acryloxyhydroxyalkyl and alkylacryloxyhydroxyalkyl, C3-C12. The method comprises: (a) acylating a hydroxyalkylene cyanoacetate with an acylating agent to form an acylated intermediate whose hydroxy radical is protected by an acyl group which is convertible to hydroxy by hydrolysis, (b) condensing the acyl intermediate with a benzophenone, (c) hydrolyzing the condensed compound to form the corresponding condensed hydroxy compound; and, (d) esterifying the hydroxy compound with an acryloyl halide or an acrylic acid to provide the desired product.

A method of making copolymerizable ultraviolet light absorber (2-cyano-3,3-diphenylacryloxy) alkylene acrylic acid esters in high yield having the formula: [Figure] where (Ar)1 and (Ar)2 are aromatic carbocyclic nuclei of the benzene and naphthalene series and are independently selected from phenyl
A method of making copolymerizable ultraviolet light absorber (2-cyano-3,3-diphenylacryloxy) alkylene acrylic acid esters in high yield having the formula: [Figure] where (Ar)1 and (Ar)2 are aromatic carbocyclic nuclei of the benzene and naphthalene series and are independently selected from phenyl or phenyl substituted with alkyl, halo, alkoxy, carboxy, carbalkoxy, cyano, acetyl, benzoyl, phenyl, alkyl phenyl, phenoxy phenyl, alkyl substituted phenoxy, or alkoxy phenyl substituted phenyl, and naphthyl; X is alkylene, C2-C17, unsubstituted or substituted with halo, cyano, alkyl, alkoxy, alkoxyalkyl, or alkoxyalkyleneoxy, C1-C6; and, Y is copolymerizable radical selected from acryloyl, alkylacryoyl, acryloxyalkyl, acryloxyhydroxyalkyl and alkylacryloxyhydroxyalkyl, C3-C12, which comprises the steps of: (a) acylating a hydroxyalkylene cyanoacetate having the formula: [Figure] where X is as defined above, with an acetyl acylating agent capable of reacting with the hydroxy group to form an acetyl acylated intermediate which is convertible to hydroxy by hydrolysis, (b) condensing the acetyl acylated intermediate with a benzophenone having the formula: [Figure] where (Ar)1 and (Ar)2 are as defined above, to form a condensed intermediate which is [Figure] (c) hydrolyzing the condensed intermediate to form the corresponding condensed hydroxy compound which is [Figure] and; (d) esterifying the condensed hydroxy compound with an acryloyl halide or acrylic acid having the formula: YZ where Y is as defined above and Z is a halide or hydroxyl group, to form said desired compounds.
