The synthesis of M(PR 3 ) 2 Cl 2 (M = Pd and Pt, R = alkyl or aryl) front K 2 MCl 4 (in H 2 O) and PR 3 (in CH 2 Cl 2 ) was promoted by the addition of phase‐transfer catalysts (PTC). The greater the amount of PTC used, the more quickly the reaction completed. 31 P NMR spectra of some M(PR 3 ) 2 Cl 2 in the presence of free PR 3 were measured; these NMR resulls were used to explain problems encountered during the preparations.
