Description
技术领域
本发明属于CO的转化及相关化学技术领域,涉及到一种CO作为C1源的α,β-不饱和炔酮化合物的制备方法。
背景技术
通过钯催化卤苯、端炔与一氧化碳的三组分插羰Sonogashira偶联反应,合成一系列具有药用价值的α,β-不饱和炔酮化合物已有较多报道[参见:(a) Kobayashi T.;TanakaM.,J.C.S.Chem.Comm.,1981,(7):333.(b)Rahman M.T.;Fukuyama T.;Kamata N.et al.,Chem.Commun.,2006,(21):2236.(c)Hao W.;Sha J.;Sheng S.et al.,J.Mol.Catal.A:Chem.,2009,298(1-2):94.(d)Zhao H.;Cheng M.;Zhang J.et al.,Green Chem.,2014,16(5):2515.(e)Bai C.;Jian S.;Yao X.et al., Catal.Sci.Technol.,2014,4(9):3261.(f)Yang S.;Cao C.;Wei F.et al., ChemCatChem,2014,6(7):1868.(g)Hao Y.;JiangJ.;Wang Y.et al.,Appl. Organomet.Chem.,2015,29(9):608.]。但报道的文献中,需要使用膦配体或者需要预先制备复杂的负载催化剂来催化反应。2008年,Xia等报道了使用负载的 Pd/Fe3O4催化体系催化碘苯、CO与苯乙炔插羰Sonogashira偶联反应,该反应与均相的钯催化体系相比避免了膦配体的使用且催化剂可重复使用多次,但该反应需要较高的反应温度和CO压力[参见:(a)Liu J.,Peng X.,Sun W.et al.,Org. Lett.,2008,10(18):3933.]。因此,开发一种条件温和、无外加配体的纳米催化体系催化碘代芳烃、CO与端炔插羰Sonogashira偶联反应,进而高效的合成α,β- 不饱和炔酮化合物具有重要意义。
