The present invention relates to means and methods for conjugating/attaching target molecules such as proteins to a label and/or carrier. Specifically, the present invention provides a complex comprising a metal cation coordinating (i) a metal cation ligand being a carbonate selected from CO.sub.3.sup.2− and HCO.sub.3— and (ii) a metal cation chelating domain comprising a chelating ligand and a label and/or carrier. This complex can be used for attaching a label and/or a carrier to a target molecule, preferably a protein. The attachment of the label or carrier via the complex of the invention involves the replacement of the metal cation ligand with a coordinating group of the target molecule so that a product complex with the target molecule as primary ligand in the coordination sphere of the metal cation is formed. Accordingly, the present invention also provides for uses and methods involving the attachment of a label and/or carrier to a target molecule. Also provided are the products obtained by the labeling and or carrier-attaching methods of the invention and uses thereof. The invention further relates to methods for producing the complex of the invention and kits comprising the components for producing the complex of the invention.

Provided are a complex prepared from ammonium salt-containing ligands and having such an equilibrium structural formula that the metal center takes a negative charge of 2 or higher, and a method for preparing polycarbonate via copolymerization of an epoxide compound and carbon dioxide using the complex as a catalyst. When the complex is used as a catalyst for copolymerizing an epoxide compound and carbon dioxide, it shows high activity and high selectivity and provides high-molecular weight polycarbonate, and thus easily applicable to commercial processes. In addition, after forming polycarbonate via carbon dioxide/epoxide copolymerization using the complex as a catalyst, the catalyst may be separately recovered from the copolymer.
