    Description / Table of Contents: The synthesis of cationic phosphite-substituted compounds [(OC)nL6-nRe]BF4, n=4, L=P(OEt)3 (2a), L=P(OPh)3 (2c); n=3, L=P(OEt)3 (2b), L=P(OPh)3 (2d); is described. With boron hydride reagents these complexes are transformed into formyl compounds (OC)nL5-nReCHO, n=3, L=P(OEt)3 (3a), L=P(OPh)3 (3c), n=2, L=P(OEt)3 (3b), L=P(OPh)3 (3d, e). The reactions of lithium dimethylcuprate with 2a and 2b affords the corresponding acetyl derivatives (OC)n[P(OEt)3]5-nReCOCH3, n=3 (4a), n=2 (4b). The structure of 3b is confirmed by an X-ray investigation.
    Notes: Die Darstellung von Phosphit-substituierten Kationverbindungen [(OC)nL6-nRe]BF4, n=4, L=P(OEt)3 (2a), L=P(OPh)3 (2c); n=3, L=P(OEt)3 (2b), L=P(OPh)3 (2d)] wird beschrieben. Diese Komplexe werden mit Borhydrid-Reagenzien zu Formyl-Verbindungen (OC)nL5-nReCHO, n=3, L=P(OEt)3 (3a), L=P(OPh)3 (3c), n=2, L=P(OEt)3 (3b), L=P(OPh)3 (3d, e) umgesetzt. Mit dem LicuMe2-System erhält man aus 2a und 2b entsprechende Acetyl-Derivate (OC)n[P(OEt)3]5-nReCOCH3, n=3 (4a), n=2 (4b). Der Aufbau von 3b wurde durch eine Röntgenstrukturuntersuchung belegt.
