Rober to Millini and Horst Kisch* Max-Planck-Institut für Strahlenchemie, D-4330 Mülheim, W.-Germany Carl Krüger Max-Planck-Institut für Kohlenforschung, D-4330 Mülheim, W.-Germany Dedicated to Professor Dr. Dr. h. c. mult. Günther Wilke on the occasion of his 60th birthday Z. Naturforsch. 40b, 187-192 (1985); received October 15, 1984 Diazepinones, Diazenes, Alkynes, Carbonyl-Iron Assistance Bicyclic l,2-diazepin-3-ones la—c, 2a, c are prepared by an iron carbonyl mediated reaction sequence from alkynes and cyclic 1,2-diazenes. The latter are first converted into hexacarbonyl diiron complexes which react with two molecules of an alkyne to afford tricyclic carbonyl iron compounds I —III. Oxidative degradation with bromine leads to these novel heterocycles whose structure is confirmed by an X-ray analysis of l b .

متن کامل2 , 3 - Triazoles from carbonyl azides and alkynes : filling the gap †
Electron deficient azides are challenging substrates in CuAAC reactions. Particularly, when N-carbonyl azides are applied the formation of N-carbonyl triazoles has not yet been observed. We report herein the first example of this class of reaction, with a copper-based system that efficiently enables the synthesis of N-carbamoyl 1,2,3-triazoles by [3+2] cycloaddition of N-carbamoyl azides and al...

In this study we have developed an efficient synthesis of 1,2-dihydroquinoline and dihydrobenzo[b]azepine derivatives involving the iron(III) chloride intramolecular alkyne-carbonyl metathesis reaction for the first time. Various functionalized 1,2-dihydroquinolines and dihydrobenzo[b]azepines were prepared from easily accessible substrates in the presence of environmentally friendly and inexpe...

For the past dozen years, homogeneous gold catalysis has evolved from a little known topic in organic synthesis to a fully blown research field of significant importance to synthetic practitioners, due to its novel reactivities and reaction modes. Cationic gold(I) complexes are powerful soft Lewis acids that can activate alkynes and allenes toward efficient attack by nucleophiles, leading to th...
