| Abstract: | The reaction of RCCl2 PCl2 (R = CH3, C6 H5, (CH3)3 Si) with dicobalt octacarbonyl in THF at ?78°C gave the new (RCP)Co2(CO)5 complexes, which contain the CPCo2 cluster unit, as air-sensitive red oils. The complex with R = CH3 reacted with (OC)5M-THF to give the corresponding M(CO)5 (M = Cr, W) adducts and the complex with R = C6H5 could be acetylated in the para position with CH3 C(O)Cl/AlCl3. |
