4-METHOXYPHENOXO COMPLEXES OF MONOOXOVANADIUM(V) AND THEIR REACTIONS WITH CYANOANILINES AND CYANOPYRIDINES

The new 4-methoxyphenoxomonooxovanadium(V) complexes with-the general formulae [VOCl3-x(OC6H4OMe-4)(x)] (where x = 1 --> 3) have been conven iently synthesized in good yields using VOCl3 and the trimethylsilyl d erivative of 4-methoxyphenol, Me3SiOC6H4OMe-4 as reactants in CCl4. Th e complexes were characterized by chemical analyses, conductively meas urements, IR,H-1 NMR, electronic spectra and thermal studies. Coordina tion compounds of the parent complexes with cyanoanilines and cyanopyr idines have been prepared and studied. Tentative stereochemistries are assigned in each case.
