reacts with and (Me4N)Cl (2/1/2) to give (I).Metathetical reactions of I with AgAc (Ac = OOCCH3), KBr or KI give complexes (X = Ac (II), Br (III), I (IV), all of which are obtained as mixtures of two isomers.The reaction of I with PPh3 (1/1) gives (V), which reacts with NaClO4 (1/1) to give ClO4 (VI).This can also be obtained directly by treating I with PPh3 and NaClO4 (1/1/1).A similar method (I + L + AgClO4) can be used to prepare ClO4 (py = pyridine) (VII).
