reduction of carbon–carbon double bond in 4-nitrostilbene analogs bearing nitro group with hydrazine hydrate. The results indicated that the reduction reaction was able to be achieved successfully between carbon–carbon double bond and nitro group. The efficient method has been developed for the reduction of CC double bonds with diimide, catalytically generated in situ from hydrazine hydrate by the synthesized
合成了一系列含Al,Mn,Cu和Fe的金属介孔碳催化剂,用于催化水合肼选择性还原带有硝基的4-硝基苯乙烯类似物中的碳-碳双键。结果表明,碳-碳双键与硝基之间能够成功地完成还原反应。已经开发出减少碳含量的有效方法C与二酰亚胺的双键由合成的催化剂由水合肼原位催化生成。0.15Al–MC1作为非均相催化剂在所有合成催化剂中均表现出最高的催化活性和化学选择性。在0.15Al-MC1存在下,在70°C的乙醇中,4-硝基二苯乙烯衍生物中碳-碳双键的还原率高达99%,化学选择性> 99%。另一方面,在惰性气氛下用水合肼,活性炭和FeCl 3 ·6H 2 O也容易实现4-亚硝基苯甲酸酯中硝基的高选择性还原。
