Abstract
The aerobic epoxidation of linear terminal olefins such as oct-1-ene and propene can be accomplished by Ru(TMP)O 2, as catalyst with turn-overs of 40 and 36 respectively during 1 day. The catalytic activity of Ru(TMP)O 2 after this time has nearly completely vanished. The catalytic deactivation is partly due to the formation of a carbonyl species Ru(TMP)CO. About 30% of this complex relative to the amount of starting catalyst has been developed within 1 day. Ru(TMP)CO has been isolated from a catalytic reaction mixture, characterized by spectroscopic and crystallographic means and is catalytically not active. The source of CO is the alkene substrate. On-line Fourier transform IR and gas chromatography-mass spectroscopy experiments suggest a catalytic side reaction, breaking the substrate propene in presence of dioxygen into two parts: a C (2) moiety (acetic aldehyde, acetic acid) and as the C (1) moiety the CO coordinated to the ruthenium atom of a deactivated catalyst.
