Pd-grafted functionalized mesoporous MCM-41: a novel, green and heterogeneous nanocatalyst for the selective synthesis of phenols and anilines from aryl halides in water

Abstract: The preparation of phenols and anilines from aryl halides in the presence of MCM-41-dtz-Pd as a heterogeneous nanocatalyst has been introduced.

“…However, there are several drawbacks of homogeneous catalysts, such as the purification of the final products, recycling of the catalyst and deactivation of the catalyst . Additionally, removal of palladium from organic products at the end of a reaction is highly desirable because of its high cost and toxicity . Hence, the heterogenization of homogeneous catalysts can help in their use for practical processes to overcome the problems mentioned above .…”

“…Figure shows the FT‐IR spectra of NH 2 –MCM‐41, P,N‐MCM‐41, and P,N−Pd‐MCM‐41. As shown in Figure a, the broad band at 3409 cm −1 is attributed to the O–H stretching vibrations of Si–OH and adsorbed water molecules and the bands at 1055, 786 cm −1 are ascribed to the asymmetric and symmetric stretching vibrations of the Si–O–Si bonds ,. Furthermore, a broad band at about 1654 cm −1 is due to the O–H bending vibration of the water adsorbed on the surface .…”

“…In 2015, Ghorbani-Choghamarani and co-workers designed a new type of nanocatalyst MCM-41-dzt-Pd through the immobilization of Pd(OAc) 2 on the surface of dithizone(dzt)-functionalized mesoporous MCM-41 (Scheme 6) [26]. The developed catalyst was able to convert aryl halides to the corresponding phenols in water at room temperature.…”
