Abstract

The protonation constants pKa of various aromatic substituted
organic oxides are reported. The following order of increasing
basicities of the investigated organic oxides was established:
sulphoxides, phosphine oxides, pyridine-N-oxides, selenoxides, arsine
oxides, antimony oxides and tellurium oxides. Several effects,
affecting the base strength of the investigated organic oxides, such
as back donation, electronegativity of the element, its polarizability
and inductive effect of the radicals bound to the element are
discussed.
