Description / Table of Contents:
Transition Metal-Substituted Diphosphenes, IX1). - Synthesis and Structure of Metalated 1,3-Diphospha-2-propanones. - Carbonylation of Diphosphenyl ComplexesThe diphosphenyl complexes (η5-C5Me5)(CO)2M-P=P-Ar (3) (M=Fe, Ru, Os; Ar=2,4,6-t-Bu3C6H2) react with Fe2(CO)9 to yield adducts such as (η5-C5Me5)(CO)2M[Fe(CO)4]P=P-Ar(4) as well as the 1,3-diphospha-2-propanone complexes [(η5-C5Me5)-(CO)2M-P(CO)PAr]Fe2(CO)6 (5) by catalytic carbonylation of the activated P=P double bond. The structures of 4a and 5a are established by X-ray diffraction studies.
Notes:
Die Diphosphenyl-Komplexe (η5-C5Me5)(CO)2M-P=P-Ar (3) (M=Fe, Ru, Os; Ar=2,4,6-t-Bu3C6H2) reagieren mit Fe2(CO)9 zu Addukten des Typs (η5-C5Me5)(CO)2M[Fe(CO)4]P=P-Ar(4) und den 1,3-Diphospha-2-propanon-Komplexen [(η5-C5Me5)-(CO)2M-P(CO)PAr]Fe2(CO)6 (5). Offensichtlich entsteht 5 aus 3 durch katalytische Carbonylierung der aktivierten P=P-Funktion. Von 4a und 5a wurden Röntgenstrukturanalysen durchgeführt.
