Abstract
AbstractMeasurements of the D(RNO) bond strength in some C‐nitrosocompounds have been made using an electron impact method. The appearance potential of the radical ion (R+) has been determined, the D(RNO) bond energy being obtained from the relation The values obtained are: D(C6H5NO) = 41 kcal/mole, D(t‐C4H9NO) = 34 kcal/mole, D(t‐C5H11NO) = 36 kcal/mole and D(i‐C3H7NO) = 36.5 kcal/mole. These values are in good agreement with the numerous estimations of Benson and coworkers and confirm that the CN bond strength in C‐nitrosocompounds is very much less than in nitrocompounds or in amines.
