Abstract
New functionalized amine-containing catecholates of triphenylantimony(V) Ph3Sb[4-O(CH2CH2)2N-3,6-DBCat] (1), Ph3Sb[4-PhN(CH2CH2)2N-3,6-DBCat] (2), Ph3Sb[4-Ph2CHN(CH2CH2)2N-3,6-DBCat] (3), Ph3Sb[4,5-Piperaz-3,6-DBCat] (4) and binuclear bis-catecholate Ph3Sb[3,6-DBCat-4-N(CH2CH2)2N-4-3,6-DBCat]SbPh3 (5) were synthesized and characterized by IR-, 1H and 13C NMR spectroscopy and cyclic voltammometry. Molecular structure of 4·CH3OH was determined by X-ray crystallography to be a distorted tetragonal-pyramidal. According to 1H NMR spectroscopy and CVA, complexes are active in reaction with dioxygen leading to the formation of spiroendoperoxides of 1,2,4,3-trioxastibolane type in yield of 25-37% (NMR data).
