Description
Summary:This article has been retracted at the request of the Editor-in-Chief and Author. Please see Elsevier Policy on Article Withdrawal ( http://www.elsevier.com/locate/withdrawalpolicy). Reason: Following helpful discussions with other research workers, the authors wish to withdraw the claims made in this paper. The solid material obtained by heating iron(III) chloride hexahydrate in pyridine is a mixture of products. Initially, this mixture appeared to catalyse Suzuki reactions in ethanol but attempts to repeat this work both in laboratories and elsewhere have been unsuccessful. Moreover, the trans-tetrakis(pyridine)dichloroiron(II) complex 1 prepared as previously reported [23] does not promote the Suzuki reaction in ethanol or aqueous ethanol. The authors would like to apologize for any confusion or inconvenience which may have arisen from the publication of this paper. [23] Baudisch, O.; Hartung, W.H., Inorg. Synth., 1 (1939) 184–185).
