DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Section cross-reference(s): 73, 22 Studies of photoelectron spectra indicate that the electronic ground states of para substituted phenyl alkyl ketones vary with the nature of the para substituent. For valerophenone [1009-14-9], the ionic ground state is no (IPobsd 9.3 eV). For p-methylvalerophenone [1671-77-8], the ionic ground state is IIS (IPobsd 9.02eV) followed by no (IPobsd 9.32 eV) and IIA (IPobsd 9.50 eV). For p-cyanovalerophenone [30611-20-2], the ionic ground state is no (IPobsd 9.57 eV) followed by IIS (IPobsd 9.83 eV) and IIA (IPobsd 10.22 eV) (where IIS refers to the ionic wave function which would be sym. to a plane perpendicular to that of the aryl group, IIA refers to the ionic wave function which would be antisym. with respect to .sigma. 64645-95-0 which is the cas registry number of one of substances is just one of reagents here.v, no refers to the ion with a vacancy localized on O in what would be the .sigma. plane). The electrochem. Ritter reactions of these ketones give products which correlate with the variation in ground electronic state. P-cyanovalerophenone gives the .gamma.-(alkyl) amide indicating intramol. abstraction of the .gamma. H atom, typical of no ionic states. P-methylvalerophenone gives the benzylic amide typical of II ion reactivity. Valerophenone gives .gamma.-amide together with ortho and para aryl amides. .
