Abstract: | Mass spectra of substituted benchrotrenyls RC6H5Cr(CO)3 where R?H, F, CI, I, CH3, OCH3, COOCH3, C2H5, N(CH3)2, NH2, C6H5, C(CH3)3, p-C6H4NH2, CH2C6H5, CH2CH2C6H5), 1,3,5-(CH3)3C6H3Cr(CO)3 and 1,2,3,5-(CH3)4C6H2Cr(CO)3 have been studied. It has been found that for monosubstituted benchrotrenyls there is a linear dependence of the parameter log [Cr]+/[RC6H5Cr]+) on the number of degrees of freedom of the [RC6H5Cr]+ ion. Decarbonylation of the molecular ions is not affected by the nature of the substituent R. The results are interpreted in terms of the quasi-equilibrium theory of mass spectra. |
