Abstract

Optical isomerism due to asymmetric coordination of some olefins such as propylene and trans-2-butene was first studied by Paiaro and Panunzi.l We have synthesized diastereomers of the type trans(Nolefin)[PtCl(L-prol)(olefin)] crystalline,2 and discussed the absolute configuration of coordinated olefins on the basis of circular dichroism (CD) spectroscopy.3 The complexes with such olefins as trans-2-butene and 2-methyl-2-butene gave no change in u.v. absorption and CD in organic solvents such as ethanol, chloroform and acetone. When the same olefin as the ligand was added, the CD changed, the u.v. absorption remaining unchanged. (Figure 1) This fact suggests that only the inversion of the coordinated olefin takes place.
