Title
PEG-anchored rhodium polyether diphosphinite complex as an efficient homogeneous and recyclable catalyst for hydroaminomethylation of olefins
Abstract

A recyclable rhodium polyether diphosphinite complex anchored in polyethylene glycol [RhPEGD] was studied for hydroaminomethylation of various olefins with primary and secondary amines. The protocol was optimized with respect to various reaction parameters and the general applicability of catalyst for hydroaminomethylation of different functionalized olefins with corresponding amines was investigated. During the course of reaction, catalyst was soluble with reactants/products while could be quantitatively separated from reaction media in biphasic form by addition of anti-solvent on completion of reaction. The catalyst exhibited remarkable activity and was subsequently recycled up to five consecutive cycles.

Graphical abstractA facile protocol has been developed for the hydroaminomethylation reaction of olefin with amine using RhPEGD-600 as effective homogeneous reusable catalyst. The system is applicable for wide variety of olefins and amines.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Efficient protocol for hydroaminomethylation of olefins with amines was developed. ► Biphasic separation strategy for homogenous reaction system was studied. ► General applicability of the developed protocol was investigated. ► The catalyst exhibited remarakable recyclability for five consecutive cycles.
