Abstract	Stereospecific coordination of racemic 2,3-diaminobutane has been observed in the reaction with platinum(Ⅱ) complexes of optically active 6,6'-dimethyl-2,2'-diaminobiphenyl. The reaction between [Pt (R-dmdabp) Cl2] (R-dmdabp is R-6,6'-dimethyl-2,2'-diaminobiphenyl) and unresolved bn (bn is 2,3-diaminobutane) has yielded [Pt(R-dmdabp)-(R-bn)] Cl2 only, while the reaction of [Pt(S-dmdabp)Cl2] with unresolvd bn has yielded [Pt(S-dmdabp) (S-bn)]Cl2 only. On the other hand, the standard [Pt(R-dmdabp) (R-bn)] Cl2 complex has been independently prepared from the reaction of [Pt(R-dmdabp)Cl2] with R-bn, and the standard [Pt(S-dmdabp) (S-bn)] Cl2 from the reaction of [Pt(S-dmdabp)Cl2] with S-bn. The stereospecific behavior of the racemic 2,3-diamino-butane is thus confirmed from the comparison of these Pt(Ⅱ) complexes prepared using racemic bn with the standard Pt(Ⅱ) complexes prepared using R-bn or S-bn.
