Abstract

A series of new paramagnetic tin(IV) complexes based on sterically hindered o-iminobenzoquinones (R)ImQ differed in fragments (R) in the N-aryl fragment is synthesized. The thermal transformation of the tin(IV) complex, (iso-Pr)ImSQSn(tert-Bu)2Cl ((iso-Pr)ImSQ is the radical anion of 4,6-di-tert-butyl-N-(2,6-di-iso-propylphenyl)-o-iminobenzoquinone), is studied. The thermal transformation of the paramagnetic complex in nonane results in the formation of a new tin(II) bis(aminophenolate) derivative. The synthesized complexes and the thermolysis product are characterized by EPR, IR, and 1H, 13C, and 119Sn NMR spectroscopy and elemental analysis. The structures of the (tert-Bu)ImSQSn(tert-Bu)2Cl complex and the thermal decomposition product, {(iso-Pr)AmPh}2Sn ((iso-Pr)AmPh is 2-(2,6-di-iso-propylphenyl)amino-4,6-di-tert-butylphenolate), are determined by X-ray diffraction analysis.
