in tetrahydrofuran (Ph3P)2N was added to a soln. of {Pd2Co2(CO)7(dppm)2} in THF.; {Co(CO)4}(1-) and {Pd2Co(CO)3(dppm)2Cl} identified in soln. by IR. Evapn. to dryness, followed by successive extn. of the residue with toluene, THF, and CH2Cl2 and crystn. (C5H12), always gave {Pd2Co(CO)3(dppm)2Cl} with amt. of (Ph3P)2N.;

With  NaCl in  water; acetone  byproducts: Na{Co(CO)4}; A soln. of NaCl in a mixt. of acetone and H2O was added to a soln. of {Pd2Co2(CO)7(dppm)2} in acetone.; n-C6H14 was added, and stirring led {Pd2CoCl(CO)3(dppm)2} to ppt. in the org. phase. It was collected by filtration and dried. Dissolution in toluene and filtration afforded a soln., which after addn. of n-C6H14 gave a powder. Elem.anal.;
