Iron(ii) complexes supported by pyrazolyl-substituted cyclopentadienyl ligands: synthesis and reactivity?

Dalton Transactions Pub Date: 2022-02-22 DOI: 10.1039/D2DT00199C

Abstract

The preparation of bis(pyrazolyl)cyclopentadienyl iron complexes is described. Isopropyl substitution promotes solubility of the iron chloride complex that serves as a precursor to several derivatives through ligand exchange. Modification of the cyclopentadienyl substituent to replace a pyrazolyl unit with a phenyl group favors formation of a substituted ferrocene complex.
