**Eine neue, bequeme Synthese von 4‐Alkyl‐3__H__‐phenothiazin‐3‐onen** 4‐Alkyl‐3__H__‐phenothiazin‐3‐one wurden durch eine neue und einfach durchzuführende Methode aus 3__H__‐Phenothiazin‐3‐on (**1**), Carbonsäuren und Silbernitrat in wäßrigem Acetonitril hergestellt.
Substituted 3-hydroxyquinoline-2,4(1H,3H )-diones 3 were transformed into 3-acyloxy-1,3-dihydro-2H-indol-2-ones 4 and isomeric 4-acyl-1,4-dihydro-3,1-benzoxazin-2-ones 5. The influence of the substituents and the reaction conditions on the course of the reaction was studied. In the proposed mechanis
