Abstract

1326358 Quaternary compounds AGFAGEVAERT 2 Oct 1970 [27 Oct 1969] 52569/69 Heading C2C [Also in Division G2] The compound of the formula is made by reacting 2(4-pyridyl)-benzothiazole with dimethylsulphate. The compounds of the formulae are made by reacting 1 : 10-phenanthroline monohydrate, 1-phenyl-2-(2-pyridyl)-benzimidazole and 2-(2-pyridyl)benzothiazole respectively with dibromoethane.
