Abstract

556,156. Pyrroles. ROGERS, M. A. T., YOULE, P. V., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. March 18,1942, No. 3583. [Class 2 (iii)] 2 : 4 - Diarylpyrroles are made by bringing the vapour of a 2 : 4 - diarylpyrroline. or 2 : 4 - diarylpyrrolidine into contact with a nickelcontaining dehydrogenating catalyst at 300‹C. or above. Examples give the preparation of 2 : 4 - diphenyl-, 2 - phenyl - 4 - (p - methoxyphenyl)-, and 2 - (p - methoxy phenyl) - 4 - phenylpyrrole. Other starting materials which may be used are 2- (m - - hydroxyphenyl) - 4 - phenyl-; 2 - (o - chlorophenyl) - 4 - phenyl -, 2 - (p - acetylaminophenyl) - 4 - phenyl-, 2 -#- naphthyl - 4 - phenyl-, and 2 - phenyl - 4 - # - naphthyl - pyrroline. The starting materials are made by reduction of the compounds Ar . C (X) H . CH 2 . CO . Ar<SP>1</SP>, where Ar and Ar<SP>1</SP> are aryl radicals and X is CH 2 NO 2 or CN.
