Synthesis and Reactivity of Ferrocenecarboxylate Ruthenium(II) Complexes. Catalytic Synthesis of a Ferrocenecarboxylic Enol Ester

Abstract

Summary: New ferrocenecarboxylate ruthenium(II) complexes were obtained from the reaction of [RuClH(CO)(PPh 3 ) 3 ] with ferrocenecarboxylic acid or its sodium salt. The reaction of alkenyl complexes [Ru(O 2 C(C 5 H 4 )Fe(C 5 H 5 ))(CR‘ CRH)(CO)(PPh 3 ) 2 ] with CO and catalytic synthesis of the phenylethyleneferrocenecarboxylic ester have been studied.
