以N-烯丙基乙醇胺为原料,经过卤化,再与苯硫酚钾反应制得N-(β-苯硫基)乙基烯丙胺,通过硅氢化反应和三甲氧基硅烷作用,然后水解固载,络合氯化钯,得到固载在二氧化硅上的聚-γ-N(β-苯硫基)乙基胺丙基硅氧烷钯络合物,并用XPS研究了结构.选用Ⅰ-十二烯、苯乙烯、Ⅰ-癸烯、苯基烯丙基醚、烯丙基环氧丙基醚、丁烯腈、环己烯、硝基苯等8种底物进行催化加氢,以评价其催化活性.结果表明,该催化剂选择性明显.不同溶剂中,其活性顺序为:苯异丙醇>乙醇、正己烷.该催化剂在空气中放置半年,其活性无明显变化,经简单回收可再用
N- (β-phenylthio) ethylallylamine is reacted with N, N-allylethanolamine through halogenation and then with potassium thiophenolate through hydrosilylation and trimethoxysilane, and then hydrolyzed Palladium chloride was supported and complexed to obtain poly-γ-N (β-phenylthio) ethylaminopropylsiloxane palladium complex immobilized on silica, and the structure was studied by XPS. Eight kinds of substrates such as Ⅰ-dodecene, styrene, Ⅰ-decene, phenyl allyl ether, allyl glycidyl ether, butenenitrile, cyclohexene and nitrobenzene were selected for catalytic addition Hydrogen to evaluate its catalytic activity. The results show that the catalyst selectivity is obvious. The different solvents, the activity of the order: Benzoin isopropanol> ethanol, n-hexane. The catalyst in the air for six months, no significant change in its activity, after a simple recovery can be reused
