Treatment of ketones with trimethylsilylcyanide in benzene in the presence of a Lewis acid (ZnI2) as a catalyst and subsequent heating after addition of pyridine and phosphoryl chloride have given α,β,-unsaturated nitriles in good yields, providing a general one-pot preparation of α,β,-unsaturated nitriles from ketones.
The preparation of the title π-acceptors (1)–(3) from the corresponding cyclohexane-1,4-diones and the electrical conductivities of their charge transfer complexes with tetrathiafulvalene are described.
