摘要
The electron‐impact induced loss of CO2 from phthalanil and 4‐phthalimidobiphenyl is paralleled by the formation of large amounts of CO2 on pyrolysis. CO is also a major pyrolysis product, but the loss of CO from these compounds under electron‐impact is not an important fragmentation process. The mass spectra of meta and para‐chlorophthalanils show prominent [M  CO2] peaks but the corresponding peak for the ortho isomer is of relatively low intensity. CO and CO2 are the principal gaseous products of the thermal decomposition of o‐chlorophthalanil. Copyright © 1968 John Wiley & Sons, Ltd.
