  Lithium benzenechromiumtricarbonyl as C-nucleophile in the cross-dehydrogenative coupling reactions of azaaromatics

  摘要：

  Direct, non-catalyzed by transition metals, the oxidative cross-dehydrogenative coupling reactions (CDC) of azines with lithium benzenechromiumtricarbonyl has been developed. A series of previously unknown benzenechromiumtricarbonyl derivatives of azines, as well as intermediates of these reactions, have been obtained and characterized by NMR and X-ray analysis.

  The dimethylsilylcyclopentadienide anion undergoes cleavage of the silicon-cyclopentadienyl bond upon attempted complexation with transition metals. Complexes bearing such ligands can be obtained by metallation of the cyclopentadienyl ligand in tricarbonyl(η5-cyclopentadienyl)manganese, ferrocene and ruthenocene, followed by reaction with chlorodimethylsilane. The silicon-hydrogen function can react

All metal carbonyl anions examined attack [(η6-iodobenzene)Cr(CO)3] at halogen, which is shown by aryl carbanion scavenging with t-BuOH. The reaction with K[CpFe(CO)2] gives only the dehalogenated arene, but the reaction with K[Cp*Fe(CO)2] (Cp* = η5-C5Me5) results in nucleophilic

  The reaction of (chloroarene)tricarbonylchromium with hexaalkylditin under palladium catalysis does not proceed by the expected Stille reaction with addition of an SnR3 group but, instead, affords alkylarene complexes via a postulated chromium-assisted alkyl migration.
