An oxygen atom is selectively inserted into the PB bond of a borylphosphine ( L 1 ) by reaction with Me 3 NO to afford the corresponding borylphosphinite ( L 2 ). This transformation can also be effected when L 1 is coordinated to rhodium. The ν(CO) values for trans‐ [RhCl(CO)(L) 2 ] reveal very different electronic properties for coordinated L 1 and L 2 which translate into the strikingly different performances of the complexes [RhCl(L)(cod)] (L= L 1 or L 2 , cod=1,5‐cyclooctadiene) in hydrosilylation and hydroboration catalysis.
