    Description / Table of Contents: P2J3 - a New Complex LigandP2J4 and Na2Cr(CO)5 react in benzene to the monomeric diamagnetic complex (CO)4CrP2J3. The 31P-nmr spectrum shows the presence of different bonded phosphorus atoms. The exchange of one iodine atom between the P atoms leads to a temperature dependent equilibrium with a symmetrical transition state. Triphenyl- and tricyclohexylphosphine react with (CO)4CrP2J3 to (CO)4CrPJ2 · P(C6H5)3 resp. (CO)4CrPJ2 · P(C6H11)3, probably of dimeric nature.
    Notes: P2J4 und Na2Cr(CO)5 reagieren in Benzol zu dem monomeren, diamagnetischen Komplex (CO)4CrP2J3. Das 31P-NMR-Spektrum zeigt die Anwesenheit unterschiedlich gebundener Phosphoratome. Der Austausch eines Jodatoms zwischen den P-Atomen führt zu einem temperaturabhängigen Gleichgewicht, in dem ein symmetrischer Übergangszustand auftritt. Triphenyl- und Tricyclohexylphosphin reagieren mit (CO)4CrP2J3 zu (CO)4 · P(C6H5)3 bzw. (CO)4 CrPJ2 · P(C6H11)3, wahrscheinlich dimerer Natur.
