Pentamethylcyclopentadienyl iron thiocarboxylato complexes: synthetic and characterization study

Abstract

Pentamethylcyclopentadienyldicarbonyl iron thiocarboxylato complexes Cp*Fe(CO)₂SCOR {Cp* = C₅Me₅, R = Me (2a), Ph (2b), C₄H₃O (2c), C₄H₃S (2d), CH₂CH₂COCl (2e)} are synthesized from the reaction of Cp*Fe(CO)₂SH (1) with the corresponding chloride acids. Complex 1 is obtained from the treatment of [Cp*Fe(CO)₂]₂ with elemental sulfur (S₈) followed by hydrolysis on silica. The hydrolysis of 2e with trace amount of water gave the corresponding acid derivative Cp*Fe(CO)₂SCOCH₂CH₂COOH (3). All new complexes have been characterized by IR, ¹H NMR spectroscopy and elemental analysis. The solid state structures of 1 and 3 are confirmed by X-ray analysis.
