摘要：
The appearance potentials of some substituted acetylacetonates of chromiumare: Cr(acac)3, 8.11 V; Cr(Iacac)3, 8.03 V; Cr(Bracac)3, 8.05 V; Cr(Clacac))3, 8.21 V; Cr(NO2acac)3, 8.63 V; Cr(tfacac)3, 9.09 V; Cr(hfacac)3, 10.13 V; Cr(CH3acac)3, 7.81 V. The values seem to be consistent with the ionization of an electron from the π system ofthe chelate ring. The mass spectra of these chelates are comparedwith previously reported mass spectraof Ti(acac)3, V(acac)3, Cr(acac)3, Mn(acac)3, Fe(acac)3,and Co(acac)3, and mechanisms of decomposition are discussed. © 1969, American Chemical Society.
