Abstract

A single-step synthesis of complexes of the type [LⁿRe^vO₂]⁺from trans-ReOCl₃(PPh₃)₂and the tetraamine ligands 1,4,7,10-tetraazadecane (L¹), 1,4,8,11-tetraazaundecane (L²), and 1,5,9,13-tetraazatridecane (L³) is reported. Successive protonation of the oxo ligands has been monitored spectrophotometrically: the first protonation occurs reversibly in 6 M HC1; the second (18M H₂SO₄)is irreversible. With [L²ReO₂]⁺, one diastereoisomer may be isolated by crystallization of the hexafluorophosphate salt, as deduced by ¹H and ¹³C NMR spectroscopy.
