    摘要: Substituted formamides such as dimethyl formamide prepared by the catalytic oxidation of tertiary methyl-amines, in which the catalyst is cupric chloride or other metal halide used in conjunction with an alkali metal halide or ammonium halide adjunct. The use of the adjunct increases the solubility of the corrosive catalyst in the reaction medium, reducing the corrosion effects of the process on reaction equipment, and can also enhance selectivity.

    摘要: Formamides e.g. diethylformamide are prepared by reacting a primary or secondary amine e.g.diethylamine or ammonia with (a) an alkyl formate or (b) carbon monoxide and an alkanol in the presence, as catalyst, of (i) a compound containing an amide group or (ii) a Group V element-containing Lewis base and an epoxide. The Lewis base can be a trivalent nitrogen or phosphorus-containing compound. The amidine group which can be cyclic or acyclic can form part of a guanidine group.
