Abstract

1416232 Azafluorene derivatives; pyridine and dihydro pyridine derivatives RICOH KK 15 Jan 1973 [24 Jan 1972] 2007/73 Heading C2C [Also in Division G2] Novel mononitro - 2 - azafluoren - 9 - ylidenemalonitriles are obtained by reacting mononitro - 2 - azafluoren - 9 - ones with malononitrile. Charge-transfer complexes of the compounds may be incorporated in organic sensitive materials for use in electrophotography (see Division G2). Mononitro-2-azafluoren-9-ones may be obtained by nitrating 2-azafluoren-9-one. 2-Azaflouren-9-one may be obtained by ring closure of 3-(2<SP>1</SP>,4<SP>1</SP>,6<SP>1</SP>-trimethylbenzoyl)-4-phenyl pyridine. The latter compound may be obtained by oxidizing 3-(2<SP>1</SP>,4<SP>1</SP>,6-trimethylbenzoyl)-4- phenyl-1,4-dihydropyridine, which may be produced by reacting 3-(2<SP>1</SP>,4<SP>1</SP>,6<SP>1</SP>-trimethylbenzoyl)pyridine with a phenyl magnesium halide. 3-(2<SP>1</SP>,4<SP>1</SP>,6<SP>1</SP>-Trimethylbenzoyl)pyridine may be prepared by reacting a nicotinoyl halide hydrohalide with mesityline.
