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

Asymmetrically substituted tertiary phosphines and quaternaryphosphonium salts are used extensively in applications throughout industry and academia. Despite their significance, classical methods to synthesize such compounds often demand either harsh reaction conditions, prefunctionalization of starting materials, highly sensitive organometallic reagents, or expensive transition‐metal catalysts.
