Abstract

A series of organometallic 4-fluorophenoxides, 4-fluorobenzoates, and 4-fluorothiophenoxides containingtrans-2-CH3C6H4M(PEt3)2 (M=Ni, Pd, Pt) groups was synthesized. Based on the19F NMR study, the data on the comparative polarity of the M−O and M−S bonds and comparative electronegativity of the indicated groups were obtained. The results indicate that the group electronegativities do not change in parallel to the electronegativities of the centrla metal atoms, and their sequence may vary as the nature of the heteroatom bonded to these groups changes.
