Description

多不饱和醛和酮的乙炔化
本发明涉及特定多不饱和醛和酮的催化乙炔化方法。
本发明的上下文中,多不饱和醛和酮是包含至少两个C-C双键的醛和酮。在本发明的一些实施方式中,C-C双键也可以是共轭的。
多不饱和醛和酮(具有共轭C-C双键),例如α,β-不饱和醛和酮,是相当稳定的化合物。
作为根据本发明方法的结果的反应产物是生产重要有机化合物(例如维生素A或类胡萝卜素)的有用中间体。
已知的特定多不饱和醛和酮的乙炔化是化学计量的方法,例如Grignard反应。这种公知的反应由于需要化学计算量而在反应结束时产生大量废料。此外,这种方法中使用的化合物不易于处理。
现在的目标是找到改进的乙炔化特定多不饱和醛和酮的方法,所述特定多不饱和醛和酮通过下式(I)来表示:
其中
R1表示-H、-CH3或-CH2CH3,且
R2表示-H、-CH3或-CH2CH3,且
R3表示片段
出乎意料地发现,这些特定(至少α,β-不饱和的)多不饱和醛和酮可以被催化乙炔化。
通过使用至少一种溶剂和至少一种催化剂,在压力下利用乙炔(=电石气;HCCH)进行乙炔化。
其中
R1、R2、R3如上文所限定,且
R是K或Cs、优选地K。

如上所述,式(I)的这种重要的特定化合物的催化乙炔化在现有技术中是未知的。
这种新方法是乙炔化的替代方法,催化过程具有显著的优点(起始材料较少、废物较少、工艺安全等)。
优选的是如上所述的催化乙炔化,其中式(I)

通常将催化剂(KOH或CsOH以及这些化合物的混合物)以水溶液的形式(基于催化剂水溶液的总重量,30-60重量%、优选地40-50重量%)加入反应混合物中。
根据本发明的催化剂优选为KOH(R为K)。
因此,本发明还涉及催化乙炔化(CE5),其是乙炔化(CE)、(CE1)、(CE2)、(CE3)或(CE4),其中R是K
因此,本发明还涉及催化乙炔化(CE6),其是乙炔化(CE)、(CE1)、(CE2)、(CE3)、(CE4)或(CE5),其中将催化剂以水溶液的形式(基于催化剂水溶液的总重量,30-60重量%、优选地40-50重量%的催化剂)加入反应混合物中。
