AbstractGenerating parahydrogen-induced polarization (PHIP) of nuclear spins with immobilized transition metal complexes as hydrogenation catalysts allows one to produce pure hyperpolarized substances, which can open new revolutionary perspectives for PHIP applications. A major drawback of immobilized complexes is their low stability under reaction conditions. In the present work we studied an immobilized iridium complex, Ir/SiO

Abstract Treatment of the ylide chelate complexes (CO)4 (1) with (C5H5)2Fe+PF6- leads to the organometallic radical cations 2. The oxidation process of 1 is also checked electrochemically by means of cyclovoltammetry, which exhibits a reversibel one electron oxidation between -0.1 and +0.3 V vs. SCE. These potentials are more negative than in any other complex of the general type Cr(CO)4L2 (L e.g. = PR3, CNR).
