Abstract: A method is described for autoxidizing ortho-dialkyl substituted aromatic ethers directly to their corresponding carboxylic acid anhydrides. The method comprises autoxidizing the ethers in a first step in a solution of an aliphatic monocarboxylic acid having 2 to 8 carbon atoms to form a partially oxidized reaction mixture. The autoxidation of the partially oxidized mixture is continued in a second step after the addition of an anhydride of an aliphatic monocarboxylic acid having 3 to 8 carbon atoms and at a temperature of at least 130.degree. C. to form said anhydrides.The anhydrides are used in the preparation of organic high temperature polymers such as polyamideimides, polyimides, polyetherimides, and polyetherimideamides.

Abstract: Novel processes for making arylpropionic acids are described. One process comprises carboxylating particular Grignard compounds which are the products of a catalyzed reaction between corresponding arylmagnesium bromides and ethylene. Furthermore, the reaction making the particular Grignard compounds is itself novel. Also, an improved method is disclosed for making coupled aryl compounds useful as intermediates for making compounds having a pharmaceutical use. For example, particular biaryls may be used to make some of the Grignard compounds herein from which the arylpropionic acids are made. Finally, an improved bromination is disclosed giving high yields of 4-bromo-2-fluoroaniline, which is thereafter coupled with benzene, then used to make the arylmagnesium bromide reacted with ethylene to obtain the particular Grignard compound and subsequent desired arylpropionic acid, i.e. 2-(2-fluoro-4-biphenylyl)propionic acid.

Abstract: The photopolymerization of ethylenically unsaturated compounds is effected using a combination of an aromatic ketone photosensitizer and a tetrasubstituted urea (e.g. N,N,N',N'-tetramethylurea) or N,N-disubstituted acid amide. Storage stable liquid photoinitiator compositions comprising an aromatic ketone sensitizer (e.g. benzophenone) and a tetrasubstituted urea (e.g. N,N,N',N'-tetramethylurea) are also disclosed. The use of the tetrasubstituted urea or N,N-disubstituted amide possesses advantages (storage stability, lack of discoloration on curing) over photosensitizers such as Michler's ketone which have been used previously in combination with aromatic ketone photosensitizers.
