Heteronuclear cluster systems. Part 12. Synthesis of µ-phenylphosphinediyl-bis(tetracarbonylcobalt) and 1,1,1,2,2,2,3,3,3-nonacarbonyl-µ3-phenylphosphinediyl-triangulo-dicobaltiron
Abstract
The reaction of Na[Co(CO)4] with PPhCl2 at –78 °C gives [{Co(CO)4}2PPh](1) in good yield. A solution of (1) evolves CO gas at 60 °C giving [Co2(CO)7(PPh)]. Complex (1) reacts with [Fe2(CO)9,] to form a new mixedmetal cluster complex [Co2Fe(CO)9(PPh)].
