Über die räumliche Konfiguration von Plato‐ und Palladokomplexen

Abstract

Nach ROSENHEIm und REIHLEN lassen sich gewisse Plato‐ und Palladokomplexe in optisch aktive Komponenten spalten. Es wurde aber in dieser Arbeit gezeigt, daß ihre Versuchsergebnisse in anderer Weise zu deuten sind.

The Sterochemistry of Square Complexes.

“…Unsuccessful attempts to obtain optically active platinous complexes have been reported by other workers. Ostromisslensky and Bergman (116) failed with [PtClNH3S03(py)]~, Tscherniaev (144) with [Pt(NH2OH)(NH3)(py)-(N02)]+, and finally Jensen (76) with bis(thiosemicarbazide)-and bis(2-aminomethyl-3-ethyl-4-methylquinoline)platinous ions. Significantly enough, in the last instance Jensen did note rotation differences of the same order as were observed by Reihlen and Huhn (130).…”

“…Formation of substance II would not alter the analytical results. Experiment shows (76) that on the addition of hydrochloric acid to bis(2-aminomethyl-3-ethyl-4-methylquinoline)platinous a-bromocamphor-irsulfonate (which may be contaminated with I or II, or both), the molecular rotation returns to its normal value, i.e., the value for the free bromocamphorsulfonic acid. Jensen explains this behavior as being due to the freeing of the bromocamphorsulfonic acid from I and/or II.…”
