  Unusual outcome of the thermolytic condensation of diazoarylmethanes with a [tricarbonyl(η6-2-p-tolyl)chromium]2-oxazolyl chelate of tetracarbonylrhenium

  摘要：

  A new Cr(CO)(3)-bound cyclorhenated 2-phenyl, 2-oxazoline derivative was synthesized and treated with two different phenyldiazomethanes, namely Ph2CN2 and (t-Bu)(Ph)N-2 under thermolytic conditions in apolar solvents. With the former diazomethane the reaction affords mainly a new bimetallic electron-saturated species resulting from the insertion of the Ph2C moiety into the C-Ar-Re bond of the rhenacyclic substrate. With the latter diazomethane substituted with one t-butyl group, the reaction quite unexpectedly leads to a new Re(CO)(4) metallacycle in which an ortho position is occupied by a (Ph)(t-Bu)(H)C-group, as a possible consequence of an unprecedented insertion-transposition of the Recentred moiety by C-H bond activation. The results are supported by 6 X-ray structures and analytical informations. (C) 2013 Elsevier B.V. All rights reserved.
