Pd (CO) (PPh 3 ) 3 could be isolated from the reaction mixture arising from cyclohexene hydrocarboxylation by PdCl 2 (PPh 3 ) 2 as the catalyst precursor; furthermore, it has also been prepared through direct reaction of Pd (PPh 3 ) 4 with CO in benzene. For this complex, 31 P‐ and 13 C‐NMR. spectra suggest a rapid dissociation of PPh 3 at room temperature and a tetrahedral structure at – 70° in solution.
