- W1995304186 abstract "Sterisch gehinderte Acylchloride 11 sind über die Alkylierung des Esters 1 oder durch Kettenverlängerung der Ketone 4 um ein Kohlenstoffatom in zwar vielstufigen, aber unproblematisch durchführbaren Reaktionsfolgen erhältlich. Die Einwirkung von Phosphorpentasulfid/Pyridin auf 11 führt in guten Ausbeuten zu den Thioketenen 12a–g. Reaktionsbedingungen, Grenzen und Nebenprodukte der Schwefelung von 11 werden diskutiert. Thioketene Syntheses, VI. Stable Thioketenes via Thionation of Sterically Hindered Acyl Chlorides Sterically hindered acyl chlorides 11 are accessible via alkylation of the ester 1 or via chain elongation of the ketones 4 by one carbon atom in practicable, though multi-step reaction sequences. Action of phosphorus pentasulfide/pyridine on 11 leads to the thioketenes 12a–g. Reaction conditions, limits, and side products of the thionation of 11 are discussed." @default.
