  Synthesis of syn-facial (Cr,Mn) benzyl complexes by the stereoselective thermolytic coupling of unsymmetric diazomethanes with cyclomanganated (η6-arene)tricarbonylchromium complexes

  摘要：

  The heat-promoted reaction of 1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene with cyclomanganated 2-[tricarbonyl(eta(6)-phenyl)chromium]pyridine afforded, upon departure of a molecule of CO, a new stable manganese alkylidene complex in which, according to X-ray diffraction analyses, the heterocyclic ligand is anti-facial with respect to the Cr(CO)(3) moiety. Similar heat-promoted reactions of unsymmetrically substituted diazoalkanes such as (Me3Si)(H)CN2, (Ph)(Me)CN2, (Ph)(t-Bu)CN2 and (Ph)(FcCH(2)CH(2))CN2, which are precursors of more electrophilic alkylidenes, with cyclomanganated 2-[tricarbonyl(eta(6)-phenyl)chromium]pyridine derivatives afforded new syn-facial heterobimetallic benzyl complexes. The stereoselectivity of these reactions depends on the steric demand of the substituents at the diazoalkane. A phenyl substituent at the diazoalkane favors the formation of syn-facial heterobimetallic benzyl complexes with the Ph group in the endo position. Combining this "phenyl directing effect" to the steric effect operated by a bulky group at the phenyldiazoalkane, like noticed with (Ph)(t-Bu)CN2, led to total stereoselectivity. This study discloses four new X-ray structures of syn-facial Cr,Mn benzyl complexes, which all present the same short Cr-to-Mn distance of ca. 3.04 angstrom. (c) 2005 Elsevier B.V.

  insertion of a Ph(MeO)C:  moiety into the CAr−Mn bond. X-ray diffraction analyses reveal that the two compounds are pseudoconformers which differ from the position of the Mn(CO)3 moiety:  in one compound, the Mn(CO)3 group is located close to the Cr(CO)3 group, while in the other compound, it is part of a nearly planar six-membered manganacyclic ring coplanar with the π-coordinated arene.
