The(akoxycarbonyl) cobalt tetracarbonylnBuOC(O)(Co(CO)4(Ia) was treated with the ligands ER3 (E = P, As, Sb; R= alkyl, aryl, alkoxy, dialkylamino) to give 37 monosubstituted products (IIa). Disubstituted derivatives (IIIa) containing PR3(R = Et, OMe)ligands were also made from Ia. The IR spectra of compouns IIa containing various PR3 ligands were correlated with the electronic and steric parameters of the P-ligands
