METHOD FOR PREPARING 1-ADAMANTANE CARBOXYLIC ACID NITRILE Russian patent published in 2008 - IPC C07C253/00 C07C253/04 C07C255/31

Abstract RU 2316540 C1

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to a method for synthesis of 1-adamantane carboxylic acid nitrile of the general formula: . Method involves interaction of adamantine with acetonitrile in the presence of CBr₄ and using molybdenum-containing catalyst of the formula Mo(CO)₆ in the following ratio of reagents: [Mo(CO)₆]:[AdH]:[CBr₄]:[CH₃CN] = (1:50)-(100:50)-(100:2000), respectively, at temperature 140^°C for 2-6 h. Method provides preparing the end product with the high yield under optimal conditions.

EFFECT: improved method of synthesis.
