A robust alcohol amination protocol using common saturated cyclic amines and primary alcohols as starting material is described for synthesis of 29 compounds. The reactions are catalyzed by combination of dichloro(p ‐cymene)ruthenium(II) dimer precatalyst with triphenylphosphine ligand. The catalyst can be precipitated by addition of hexane or cold diethyl ether, followed by isolation of the product

There are provided a method of producing a carbonyl compound by a flow type reaction, including introducing a triphosgene solution into a flow channel (I), bringing the triphosgene solution into contact with a solid catalyst immobilized in at least a part of the flow channel (I) to generate a phosgene solution while the triphosgene solution is flowing through the flow channel (I), joining the phosgene solution and an active hydrogen-containing compound solution that flows inside the flow channel (II), which are subsequently allowed to flow downstream inside a reaction flow channel to be reacted in a presence of a tertiary amine, and obtaining a carbonyl compound in a joining solution; and a flow type reaction system that is suitable for carrying out this production method.
提供了一种通过流动型反应生产羰基化合物的方法,包括将三光气溶液引入流动通道(I),在三光气溶液流经流动通道(I)时,使三光气溶液与固定在流动通道(I)至少一部分中的固体催化剂接触,生成光气溶液、将光气溶液与流道 (II) 内的活性含氢化合物溶液汇合,然后让它们顺流进入反应流道,在叔胺存在下进行反应,并在汇合溶液中获得羰基化合物;以及适用于该生产方法的流动式反应系统。
