Facile nucleophilic substitution of coordinated acetonitrile in trans-[PtCl4(NCMe)(PPh3)]
( )Despite the generally accepted inertness of platinum(IV) complexes towards nucleophilic substitution, the title compound promptly reacts with nucleophiles L (L = pyridine, quinoline, isoquinoline, benzothiazole, o-, m-, ptoluidine) affording the corresponding acetonitrile substitution products. To follow the reaction spectroscopically, a series of platinum(IV) standards were prepared by bridge splitting of trans-[Pt(mu-Cl)Cl(PPh3)](2), followed by oxidation by PhICl2. All the new platinum(II) and platinum(IV) complexes were fully characterized, and, in some cases, the structure was studied by single crystal X-ray diffraction. Even when protic o-, m- and p-toluidines were used, chemoselectivity towards substitution was observed, with addition products formed in less than 10% extent.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 1897-52-5. Formula: C7H3F2N.
