THERMAL TRANSFORMATIONS OF OXAZOLE ENDOPEROXIDES: REARRANGEMENTS, FRAGMENTATIONS AND METHANOL ADDITIONS

Oxazole endoperoxides 1 carrying a phenyl group at C-2 rearrange to triacylamines 3; those carrying a hydrogen atom at C-2 undergo a fragmentation into 1:1 mixtures of nitriles (or HCN) 4 and anhydrides 5, whereas methyl substitution at C-2 gives rise to competition between these two modes of reaction.Methanol addition to 1 leads to 4-methoxy-5-hydroperoxides 6 which easily transform into methyl esters 7 and diacylamines 8.

Reaction of Diazonium Salts with Transition Metals. 6. Preparation of Mixed Acid Anhydrides from Arenediazonium Salts and Sodium Carboxylates under Palladium(0) Catalysis

The palladium(0)-catalyzed reaction of arenediazonium tetrafluoroborates with carbon monoxide and sodium carboxylates in acetonitrile at 25 deg C gave mixed acid anhydrides, ArCOOCOR (Ar = 3-Me-Ph, 4-Me-Ph, 2-MeO-Ph, 4-Br-Ph, 4-I-Ph, 3-NO2-Ph, 4-NO2-Ph, and Ph; R = H, Me, Et, t-Bu, and Ph) in good yields.Homoaromatic acid anhydrides, (ArCO)2O, were obtained by heating of ArCOOCOMe at 100-120 deg C under vacuum.ArCOOCO-t-Bu can be utilized to obtain the corresponding arenecarboxamides by the reaction with some amines.
