摘要:
The reactions of clusters (μ3-CCO2Et) Co2M (CO)5 (MeCp) [M=Mo (2a),W (2b)],derived from the reaction of (μ3-CCO2Et) Co3 (CO)9 with Na [M (CO)3 (MeCp)],with Na2 [Fe (CO)4] in THF at reflux not only gave the expected metal fragment exchange products (μ3-CCO2Et) FeCoM (CO)6 (Me-Cp) H [M=Mo (3a),W (3b)] but also produced the unexpected compounds (μ3-CCO) FeCoM (CO)5 (MeCp) [M=Mo (4a),W (4b)].It is suggested that the formation of two kinds of compounds resulted from two competitive reactions of the intermediates [(μ3-CCO2Et)FeCoM (CO)5(MeCp)] with H+:the one is the protonic reaction of the intermediate giving the cluster 3a,b;the another one is the intermolecular nucleophilic substitution reaction of the intermediate under the H+ catalytic action giving the cluster 4a,b.
