Abstract

The reaction of sodium salts of substituted malononitriles with cyanogen chloride provides a new, general synthesis of alkyl-and aryltricyanomethanes. As a modified method, benaotricyanides are prepared drectly from arylacetonitriles, sodium hydride, and cyanogen chloride. The tricyanomethyl group is meta directing to electrophilic substitution reactions on the aromatic ring and inductively withdraws electrons much mare strongly than nitro or ...
