amines, and 5) amine oxides to amines. The above-mentioned rhodium catalyst system was heterogenized by using amino-substituted polystyrenes. Rh6 and Rh14 carbonyl clusters of [Rh6(CO)15H]−, [Rh6(CO)15]2−, and [Rh14(CO)25]4−, were formed on the polymer surface. The characteristic features of the catalysis of the polymer-bound rhodium cluster complexes are described in relation to the corresponding homogeneous
研究了在水煤气变换反应下使用羰基铑化合物对各种 N-O 键的催化脱氧。发现 Rh6(CO)16 和 N,N,N',N'-四甲基-1,3-丙二胺的催化剂体系对以下脱氧反应具有高活性:1) 硝基苯转化为苯胺,2) 脂肪族硝基化合物转化为腈,3) 肟转化为腈,4) 羟胺转化为胺,以及 5) 氧化胺转化为胺。上述铑催化剂体系通过使用氨基取代的聚苯乙烯多相化。[Rh6(CO)15H]-、[Rh6(CO)15]2-和[Rh14(CO)25]4-的Rh6和Rh14羰基簇在聚合物表面形成。聚合物结合的铑簇配合物的催化特征与相应的均相配合物有关。
