Complexes of tripodal phosphine ligands: synthesis, structure and catalytic activities in the hydroboration of CO$_2$
Abstract
Tripodal ligands play a major role in transition metal chemistry by increasing the stability of their complexes and enabling a fine control of the reactivity at the metal center through their steric and electronic properties and their specifie coordination geometry. Among these ligands, triphos (MeC(CH$_2$PPh$_2$) has attracted considerable attention over the last years as it was successfully used for several applications in catalysis, including CO$_2$ hydrogenation, disproportionation of formic acid and reduction of amides. Because small changes within a ligand can induce different outcomes in a catalytic reaction, variations on the triphos backbone have been reported. In this study we report the use of PhSi(CH$_2$PPh$_2$)$_3$ and its phosphinite derivative PhSi(OPPh$_2$)$_3$h in the coordination chemistry of first-row transition metals, namely iron(II), cobalt(lI) and copper(I).
