2,2,6-Trimethyl-4H-1,3-dioxin-4-one 화학적 특성, 용도, 생산

• 화학적 성질

  Dark brown liquid

• 용도

  Diketene-Acetone Adduct can be used in place of diketene in many reactions. As a transportable form of diketene, it is especially important in those countries, where the transportation of diketene is not allowed or at least not desired.

• 주요 응용

  2,2,6-Trimethyl-4H-1,3-dioxin-4-one generates unstable acetylketene together with acetone when heated above 120 ℃. Subsequent condensation with isocyanates, arylcyanates, or substituted cyanamides gives access to a wide range of 1,3-oxazine derivatives. Furthermore, diketene – acetone adduct can also be used for the preparation of a variety of compounds that are not accessible from diketene.

• 화학 반응

  Diketene – acetone adduct (2,2,6-Trimethyl-4H-1,3-dioxin-4-one) can be regarded as a stabilized form of diketene. It can be safely transported and may conveniently be used instead of diketene in many reactions. For example, it reacts with alcohols and amines to yield acetoacetates and acetoacetamides, respectively. Diketene – acetone adduct generates unstable acetylketene together with acetone when heated above 120 ?C. Subsequent condensation with isocyanates, arylcyanates, or substituted cyanamides gives access to a wide range of 1,3-oxazine derivatives. Furthermore, diketene – acetone adduct can also be used for the preparation of a variety of compounds that are not accessible from diketene.
