Ph3P=NSiMe3 reacts with acetyl and p-tolyl salicylic acid chlorides to afford the corresponding benzoxazinones: This new reaction allows the first preparation of the compound in which R1=Me, since the formation of the dimer, only provided by the unique route previously described, can be avoided.In contrast, o-acyl derivatives of lactic acid chlorides react with Ph3P=NSiMe3 to give the corresponding nitriles and not the expected oxazolones, as previously described.
