o-Phenylenediamine condenses with ketones and aldehydes to give rise to a variety of useful products. Its reactions with carboxylic acids and their derivatives produce benzimidazoles. The herbicides benomyl and fuberidazole are made in this manner. Thiophanate-methyl is another herbicide produced from o-phenylenediamine. Quinoxalinedione may be prepared by condensation of o-phenylenediamine with dimethyl oxalate. … Web1 day ago · Sternbach-Reeder rearrangement of 2-chloromethyl substituted derivatives of benzimidazolo annulated analog of quinazoline 4(a-e) with propargyl amine … how to request financial assistance
