Chemical Behaviors of 1, 1'-Diacetyl-1, 1', 4, 4'-tetrahydro-4, 4'-bipyridine toward Organic Hydrogen Acceptors

Abstract

Chemical behaviors of 1, 1'-diacetyl-1, 1', 4, 4'-tetrahydro-4, 4'-bipyridine toward organic hydrogen acceptors such as nitrosobenzene, p-benzoquinone, dibenzoyldiimide, and 5-benzylidene-1, 3-dimethylbarbituric acid were examined to demonstrate its ability in donating hydride and acetylium ion. Reduction processes of these substrates are described and, with the latter two, reductive acetylations of a new fashion are disclosed.
