标 题:Intermediates for the preparation of 1,3-dihydro-2H-1,4-benzodiazepin-2-ones
发明人：MCCAULLY RONALD J

摘要:Two routes for the preparation of 2-(2-acylamido-2-amino)acetamidophenyl aryl ketones, used as intermediates in the synthesis of psycholeptic 1,3-dihydro-2H-1,4-benzodiazepin-2-ones are described. The first of these routes involves the formation of a 2-(2,2-diacyloxy)acetamidophenyl aryl ketone from glyoxylic acid and an aryl phenyl ketone via either a 2,2-diacyloxy acetyl halide or a 2,2-diacyloxy acetyl anhydride, coversion thereof to the corresponding 2-(2-acylamido-2-hydroxy) acetamidophenyl aryl ketone directly or via the 2-(2,2-dihydroxy)acetamidophenyl aryl ketone, formation of the corresponding 2-(2-acylamido-2halo)acetamidophenyl aryl ketone, and conversion to the 2-(2acylamido-2-amino)acetamidophenyl aryl ketone. The second route forms the 2-(2,2-dihydroxy)acetamidophenyl aryl ketone by reacting a 2,3-dicarboxylicacyl tartaric anhydride with a 2aminophenyl aryl ketone to obtain a 2-(3-carboxy-2,3acyloxy)propionamidophenyl aryl ketone, selectively hydrolyzing the so-obtained ketone and selectively oxidizing the product with a vic glycol cleaving agent.

摘要:A composition having a mixture of the below compounds having a mole ratio of at least 1:20. Ar 1 and Ar 2 are independently selected aromatic groups. A composition comprising phthalonitrile compounds that comprise at least 5 mol % of the first compound below. n nA method of: providing a solution of a dichloroaromatic compound having an electron-withdrawing group bound to each aromatic ring containing one of the chloride groups; a dihydroxyaromatic compound or anion thereof; an organic transition metal complex or a transition metal salt; an alkaline hydroxide base; and a solvent; and heating the solution to a temperature at which the dichloroaromatic compound and the dihydroxyaromatic compound react to form a dimetallic salt of an aromatic ether oligomer. The molar ratio of the dihydroxyaromatic compound to the dichloroaromatic compound is greater than 2:1. Water formed during the heating is concurrently distilled from the solution.

摘要:A method of: providing a solution of a dichloroaromatic compound having an electron-withdrawing group bound to each aromatic ring containing one of the chloride groups; an excess of a dihydroxyaromatic compound; an organic transition metal complex or a transition metal salt; a base; and a solvent; and heating the solution to a temperature at which the dichloroaromatic compound and the dihydroxyaromatic compound react to form an aromatic ether oligomer that is a dihydroxy-terminated compound or a dimetallic salt thereof. Water formed during the heating is concurrently distilled from the solution. A method of curing a phthalonitrile monomer in the presence of an acid and a curing agent to form a phthalonitrile thermoset.
