  发展绿色、高效、高选择性的合成新反应、新方法是目前有机合成化学研究的前沿课题。过渡金属催化醛对烯烃的氢酰化反应是合成酮类化合物的原子经济性反应。但是,目前这类反应主要使用铑催化剂,且要求底物带有导向基团,并且反应的区域选择性也有待提高。最近,我们研究发现零价镍的单膦配体络合物可以催化分子间的醛与烯烃的氢酰化反应,底物不需要有导向基团,反应具有很高的收率和区域选择性。

气凝胶(aerogel)因其独特的结构和性能,在隔热材料、催化剂载体、储能储氢材料等方面有广泛的应用前景。有机气凝胶比传统无机气凝胶具有更好的力学性能和加工性能,因此越来越受到关注[1-3]。
高效催化转化纤维素,开拓纤维素综合利用的新途径及新技术成为近年来研究领域的热点问题。在我们前期工作中,Ni/ZSM-5水解加氢纤维素制备六元醇获得了较好结果[1],然而传统ZSM-5存在孔道尺寸小,酸性位分布不均,扩散难,易积碳等问题,引入多级介微孔是最有效的改性策略之一[2]。
