N2 - A number of compounds of the type [Co(C6Cl5)2L2] (L PEtPh2, PEt2Ph, PEt3, py, β-pic, λ-pic, 3,5-lut, or L2 dpe and bipy) have been prepared by reacting C6Cl5MgX with [CoCl2L2] or by adding the stabilizing ligand to a solution of "Co(C6Cl5)2". Ligand exchange reactions show that a more basic displaces a less basic ligand. The compounds with L PEt2Ph, PEt3, dpe, and bipy remain unaltered in boiling benzene, but when L PEtPh2 and 3,5-lut, partial decomposition occurs. The decompositions give only C6HCl5 when L py, β-pic, λ-pic, and 3,5-lut, but a mixture of C6H1+nCl5n and C12HnCl10 n is obtained when L PEtPh2; the coupling occurs after the dissociation of the ligand. Decomposition in benzene in the presence of bromine gives C6BrCl5 when L is an amine, but C12HnCl10n when L is a phosphine.
