The reaction of nitriles without α hydrogen atoms on phosphol 3 enes oxides or sulfides anions yields 1-aza 2-phospha cyclohepta 4,6 dienes. 1–2 or 1–4 addition to the pyridine ring may occur with nicotino- and isonicotinonitriles, instead of attack on the nitrile function in this reaction. Trichlorosilane does not reduce these seven membered P oxides to the corresponding phosphines but causes a ring
