Alkinyltriazene in photochemischen metallfreien Doyle‐Kirmse‐Umlagerungen
Angewandte Chemie, EarlyView.Es wird eine metall‐ und additivfreie photokatalytische Doyle‐Kirmse‐Reaktion von Alkinyltriazenen beschrieben, die über Cyancarbenzwischenstufen verläuft. Diese Strategie ermöglicht den effizienten Aufbau hochsubstituierter asymmetrischer Kohlenstoffzentren mit breitem Substratspektrum und liefert synthetisch wertvolle Nitrile.

Studies on Girard Hydrazones. II. Polarographic Reduction Mechanisms of Girard Hydrazones
Chemical and Pharmaceutical Bulletin, 1964 Polarographic reduction processes of Girard hydrazones of aliphatic and aromatic ketones were studied. From the results of controlled potential electrolysis, the two-electron reduction process proposed by Prelog and Hafliger for Girard-T Hydrazones of aliphatic and alicyclic ketones was found to be not correct, and a mechanism shown in scheme (4 ...
