✦ Synopsis

A facile synthesis of highly soluble, axially substituted titanium(IV) phthalocyanines is described. The reaction of tetratert-butylphthalocyaninatotitanium oxide tBu 4 PcTiO with the chelating agents 3a-3i containing oxygen or sulfur as donor atoms leads to the formation of axially substituted tBu 4 PcTiX (X = functionalized catechols, dithiocatechol, and dihydroxynaphthalene). Following the same procedure a dimeric sandwich-like complex could be also synthesized from the reaction of tBu 4 PcTiO with tetrahydroxy-p-benzoquinone. All compounds were characterized by IR, UV/Vis, MS, 1 H and 13 C NMR spectroscopy, and elemental analysis. The axially [a]

2,6-Dibromopyridine N-oxide and 4-nitro-2,6-dibromopyridine N-oxide were treated with tributyl(pyridin-2-yl)stannane under the conditions of the Stille coupling reaction. Derivatives of 2,2Ј-bipyridine 1-oxides as well as 2,2Ј:6Ј,2ЈЈ-terpyridine 1Ј-oxides were synthesised. Oxidation of 2,2Ј:6Ј,2ЈЈ-t
