Abstract
A series of organometallic 4-fluorophenoxides, 4-fluorobenzoates, and 4-fluorothiophenoxides containing trans-2-CH3C6H4M(PEt3)(2) (M = Ni, P d, Pt) groups was synthesized. Based on the F-19 NMR study, the data o n the comparative polarity of the M-O and M-S bonds and comparative el ectronegativity of the indicated groups were obtained. The results ind icate that the group electronegativities do not change in parallel to the electronegativities of the central metal atoms, and their sequence may vary as the nature of the heteroatom bonded to these groups chang es.
