An optical rotatory dispersion and circular dichroism investigation of the chloramidation of the triamine EnPYClNO2ClPtCl

Conclusions An optically active product from the chloramidation of (-)₅₈₉ EnPyClNO₂ClPtCl with the composition (+)₅₈₉ (NH₂C₂H₄NCl)·PyClNO₂ClPt has been isolated in the solid state for the first time. The optical activity of a solution of this compound in DMF has been investigated using CD and ORD. A sharp change in the spectrum of the optically active bands of the reagent takes place during chloramidation which is apparently not only associated with the change in the nature of the Pt-chelate bond but also with the appearance of a new chromophore (the chlorimido group), the absorption bands of which can become optically active as a result of the vicinal effect.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimieheskaya, No. 4, pp. 928–931, April, 1970.
