  First α,β-unsaturated mononuclear bisylidene complex of tungsten: synthesis and structure

  摘要：

  cis-Tetracarbonyl [(1-cyclopentenyl)(N-morpholino)methylidene](2-hydroxyphenyl isocyano)tungsten(0) 5 undergoes intramolecular cyclization by deprotonation and subsequent N-alkylation to give the novel bisylidene complex 6, which is characterized by a single-crystal X-ray structure analysis.

  Vinylaminocarbenes of Group 6 Metals by Metathesis Reaction of 2-Amino-1,3-butadienes. Reactivity toward Electron-Deficient Alkenes

  摘要：

  A new method for the synthesis of chromium, molybdenum, and tungsten Fischer-type vinylaminocarbenes 3 by the metathesis reaction of 2-amino-1,3-butadienes and phenyloxycarbenes is reported. In addition, the reaction of 3 with electron-deficient alkenes to afford, after hydrolysis, the vinyl ketones 6 has been studied. In order to explain this behavior, a cyclopropanation process has been proposed, which is supported by the formation of the seven-membered ring 8 from diene 7.
