    摘要： A process for producing an indole which comprises reacting an aniline and a diol in the presence of a catalyst to produce a reaction mixture containing the indole, unreacted aniline and by-products, condensing the reaction mixture to obtain a liquid reaction product, recovering the unreacted aniline from the liquid reaction product, reducing the contents of specified by-products in the recovered aniline below specified levels and reutilizing the resulting recovered aniline. To reduce the contents of the specified by-products in the recovered aniline below specified levels, it is preferred to subject the liquid reaction product or an aniline fraction separated therefrom to a heat-treatment and then to distillation. In the above manner, the recovered aniline can be reutilized in the reaction without causing the activity of the catalyst to deteriorate.

    摘要： It is an object of the present invention to provide a catalyst for a cross-coupling reaction in which an organometallic complex is sufficiently immobilized on a carrier and an object product can be easily obtained in a high yield and in a relatively short reaction time with a relatively small amount of use. The catalyst for a cross-coupling reaction of the present invention has a carrier part composed of a synthetic resin and an organometallic complex part immobilized on the carrier part by chemical bonding, and has a structure represented by formula (P1), wherein in (P1) R 1 , R 2 may be the same or different, and is a substituent such as a hydrogen atom. R 3 , R 4 , R 5 , R 6 , R 8 , R 9 may be the same or different and are substituents, such as a hydrogen. X represents a halogen atom, and R 7 represents a substituent having 3 to 20 carbon atoms with a Π bond. RS1 represents the main chain of the synthetic resin precursors having -CH 2 OH group at their end.
