Preparation of Some Nickelocene Derivatives

Abstract

Reaction of thiols RSH (R=i-CsH7, tert-C'Hg, CizH2s and p CH3C6H) with nickelogene giave They the corresponding thiolate derivatives of nickelocene with the formula of (CsHsNisR)2were blac- shin crystals with moderate stability, and solub1e in most orgapic solvep. ts. Products with oiygeri-containing thiols (R=HOCH2CH2 and HO2CCH2) were black crys-talline mass with the f=of (CsHsNiSR).. They were fairly unstable, particularly in solution, atid gave insoluble and infusible black mass on standing.
ReVaction of nickelocene with methanol in inert solvents in the presence of oxygen gaye red liquid and analytical data, f the pr duct are in go, d agreement with thoseof the. mofio-methoMxy of derivative of nickelocene. Analogous reaction with p-benzoquinone quantitatively gave an equimolar adduct as brown powder.
