二烯酮的合成研究

Study on Synthesis of the Diketene

烯酮是一种化学性质非常活跃的有机合成试剂,早在本世纪初即已被合成出来。烯酮在光学方面所表现出来的巨大潜力,引起人们对二烯酮研究的极大兴趣。本文主要介绍以丙酮与醛为反应物,在碱性条件下发生羟醛缩合生成多种烯酮的方法,及对二烯酮重结晶方法的探究。

Ketene is a chemical property is very active reagents in organic synthesis, as early as the beginning of this century has beensynthesized. Ketene in optics shown great potential, causing a lot of interest to the dienone research. This paper mainly introduces thealdehyde and acetone as reactants and under alkaline conditions occurred aldol condensation to generate a variety of ketene method, and to thedienone recrystallization method of inquiry.
