Michael adducts of nitriles and α,β-unsaturated ketones have been found generally to undergo two or more kinds of thermal reversibility upon being heated to moderate temperatures. When the products are those from which the adduct was prepared, the

The mass spectra of 18 substituted 1-(p-R2-phyeyl)-3-R3-4-(p-R1-phenylimino)-2-pyrazolin-5-ones have been obtained. The major cleavages under electron bombardment take place in the pyrazoline nucleus, producing four major fragment ions whose abundanc

In this paper a number of known chemical facts obtained by classical methods are correlated with the mass spectra of compounds thermally decomposed in the heated inlet of the mass spectrometer. Of the 31 substances examined, 24 are dioxo compounds. A
