A simple and efficient method has been developed for the synthesis of α-amino nitriles from aldehydes, amines and trimethylsilyl cyanide (Me3SiCN) in the presence of a catalytic amount of cyanuricacid at room temperature.

An efficient, mild and environmentally friendly method has been developed for the Streckerreaction to synthesize α-aminonitriles in the presence of K2PdCl4 as a catalyst. The three-component one-pot condensation of an aldehyde, amine and trimethylsilyl cyanide proceeded smoothly in water to afford the corresponding product in high yield with short reaction times.

and methyl acrylate as starting materials. The first Michael addition between α-aminonitrile and methyl acrylate occurred mainly with Lewis base catalysts such as PBu3, DBU, and DABCO, but the subsequent Michael addition happened only with phosphine catalysts like PBu3. Furthermore, pyrrolidine derivatives were obtained from the corresponding aldehydes, amines, trimethylsilyl cyanide, and methyl acrylate
Role of (3-aminopropyl)tri alkoxysilanes in grafting of chlorosulphonic acid immobilized magnetic nanoparticles and their application as heterogeneous catalysts for the green synthesis of α-aminonitriles
organic–inorganic hybrid magnetic heterogeneous catalysts. The silanization was carried out on the surface of SiO2 coated Fe3O4 nanoparticlesusing two different trialkoxy silanes, i.e., 3-aminopropyltriethoxysilane (APTES) and 3-aminopropyltrimethoxysilane (APMES). The effect of the alkoxy silane structure anchored to the surface of silica functionalized Fe3O4 nanoparticles on their surface area and pore volume
通过接枝硅烷偶联剂对SiO 2包覆的Fe 3 O 4纳米粒子进行表面改性是提高无机磁芯与要固定的有机官能团之间的界面相互作用的非常重要的方法。然而,很少使用有机-无机杂化磁性非均相催化剂研究利用不同的硅烷烷氧基的硅烷接枝分子结构的影响。使用两种不同的三烷氧基硅烷,即在SiO 2包覆的Fe 3 O 4纳米颗粒的表面上进行硅烷化,3-氨基丙基三乙氧基硅烷(APTES)和3-氨基丙基三甲氧基硅烷(APMES)。通过BET分析仪分析了锚固在二氧化硅官能化的Fe 3 O 4纳米颗粒表面上的烷氧基硅烷结构的表面积和孔体积的影响。与APTMS相比,使用APTES进行的硅烷官能化可产生更高的表面积和孔体积。此外,将氯磺酸固定在APTES和APTMS官能化的SiO 2 @Fe 3 O 4上以水为溶剂,一锅合成α-氨基腈,成功地实现了纳米颗粒(AE和AM)的分离,并作为可磁分离的非均相催化剂发挥了作用。使用A
