Formation of a new carbon-carbon bond in the reaction of allyl halides with tin(iv) bis-o-amidophenolate

A reaction of tin(IV) bis- o -amidophenolate complex based on redox-active 4,6-di- tert -butyl- N -(2,6-diisopropylphenyl)- o -aminophenol with various allyl halides was studied. This process includes the addition of 1 equiv. of allyl halide to the starting complex and is accompanied by the change in the redox state of one of the redox-active ligands. The reaction results in the formation of a new carbon—carbon bond between the allylic fragment and the carbon atom at position 5 of the ligand o -iminoquinone ring, as well as a tin—halogen bond. The structure and composition of compounds synthesized were confirmed by ESR, NMR, and IR spectroscopy and elemental analysis.
