摘要: Abstract The kinetics of the replacement carbon monoxide by another ligand L in some carbenic binuclear compounds [(μ-η 2 -R 1 OCS)Fe (CO) 6 (μ-SR )] under thermal activation have been studied (L = P(OMe) 3 or Me CNC: R adamantyl-CH 2,4,6-trimethylphenyl: CH CN). concentrations complexes determined electrochemically. follows an associative path after equilibrium period during which a coordinatively unsaturated metal center is created reversible partial decoordination bridging μ-SR . Rate constants show that carbene not involved entry values Δ H ≠ and S calculated for reaction.
