Onium Salt-catalyzed Acylations with Diketene

, p. 2062 - 2067 (2007/10/02)
Weak NH- and CH-acids can be acylated advantageously by diketene (1) in the presence of a quarternary ammonium chloride.Carboxamides yield with one or two moles of 1 the products 3 or 10 selectively. β-Keto esters and β-diketones lead to 12a, b or 13, respectively, and acetoacetamides give 5 or 8.The polymer 16 and/or 17 is formed by self-condensation of 1.
