SYNTHESIS AND PROPERTIES OF DIALKYL(ACETYLACETONATO)BIS(TERTIARY PHOSPHINE)COBALT(III)

Abstract The complexes I-IV, CoR2(acac)(PR′3)2 (R=Me, Et, n-Pr, iso-Bu; PR′3=PEt3,P(n-Bu)3,PPhMe2,PPh2Me) have been prepared by the reactions of Co(acac)3, AlR2(OEt) and tertiary phosphines in ether. These complexes were characterized by NMR, IR spectroscopy and the chemical reactions. H-D scrambling in ethyl groups of Co(CH2CD3)2(acac)(PPhMe2)2 (V) has been observed.
