The dinuclear complex trans-[(OC)3Fe(μ-PCH2-oxazoline-P,N)2CoCl2] 9 and not the trinuclear trans-[{(OC)4Fe(μ-PCH2-oxazoline-P,N)}2CoCl2] 4 was used as ethylene oligomerization catalyst.
Therefore, the last three sentences of the Abstract should be modified to read:
The complex [{(OC)4Fe(μ-PCH2-oxazoline-P,N)}2HgI2] 5 was also prepared from 6. With the metalloligand 6, the Fe→Pd and Fe→Co metal–metal bonded compounds trans-[(OC)3Fe(μ-PCH2-oxazoline-P,N)2Pd(NCMe)](BF4)2 8 and trans-[(OC)3Fe(μ-PCH2-oxazoline-P,N)2CoCl2] 9 were obtained. This latter complex catalyses the oligomerization of ethylene to give linear α-olefins in the C4–C26 range, with a maximum of the Schulz–Flory distribution around C6.
In the third paragraph of the Results and discussion section, the correct formula for complex 4 is: trans-[{(OC)4Fe(μ-PCH2-oxazoline-P,N)}2CoCl2].
The last two sentences in the Conclusion should be transposed to read: With the metalloligand 6, the Fe→Pd and Fe→Co metal–metal bonded compounds 8 and 9 were obtained, respectively. This latter complex catalyses the oligomerization of ethylene to give linear α-olefins in the C4–C26 range, with a maximum of the Schulz–Flory distribution around C6.
The correct literature reference for the synthesis of ligand 1 given at the end of the first paragraph of the Experimental section is 17a and not 19a.
Finally, in the Catalysis section of the Experimental section, the catalyst used was trans-[(OC)3Fe(μ-PCH2-oxazoline-P,N)2CoCl2] 9.
