Aerobic reactions of CoX2 (X = OAc, Cl) or Co(ClO4)2 with (S,S)-1,2-diphenylethylenediamine [(S,S)-dpen] in CH3OH, followed by HCl or HClO4 additions, give the diastereomeric lipophobic salts Λ-[Co((S,S)-dpen)3]3+3Cl- [Λ-(S,S)-13+3Cl-] or Δ-(S,S)-13+3ClO4- (60-65%) with high degrees of selectivity. Anion metatheses (room temperature) and equilibrations… CONTINUE READING
