A Novel 0-Alkylation of Pyridine and two Ph groups), and mass spectrum [m/e 349 (M+), Quinoline 1-Oxides1 105 (PhC=0+)].Summary: Pyridine and quinoline 1-oxide react with phenylpropiolonitrile to give a rearranged 3-alkylated derivative as the main product (whose structure has been confirmed spectroscopically, by degradation, synthesis, and, in the case of the pyridine derivative, by single-crystal X-ray analysis) together with minor amounts of the expected 2-alkylation product.Sir: As ra possible extension of the intramolecular nucleophilic substitutions leading to the direct acylamination of heteroaromatic X-oxides2 we have studied the reaction of pyridine 1-oxide with phenylpropiolonitrile in boiling ethylene chloride.The expected product (1) of intramolecular sub-
