Abstract

1,247,337. 1,11-Ethylene-1,11,2,21-tetrahydro- 2,21-bipyridyls. IMPERIAL CHEMICAL INDUSTRIES Ltd. 11 Sept., 1968 [5 Oct., 1967], No. 45542/67. Heading C2C. [Also in Division C7] The invention comprises 1,11-ethylene-1,11, 2,21 – tetrahydro – 2,21– bipyridyl and alkyl derivatives thereof. They may be prepared by the reduction of the corresponding ethylene-bispyridinium salts in solution e.g. by treatment with sodium, magnesium, calcium or aluminium. The preferred reducing agent is sodium amalgam. Alternatively the reduction can be carried out electrolytically by using a neutral or alkaline aqueous solution of the salt as electrolyte. Preferably a salt having high conductance in solution, e.g. sodium chloride, is added to the electrolyte.
