... The prevalence and biological importance of carbonyl compounds in the pharmaceutical, fine chemical, and materials science industries have driven a growing interest in developing more efficient methodologies for their synthesis [1]. In this context, isomerization has emerged in recent years as an attractive and straightforward strategy for synthesizing versatile, challenging, substituted carbonyl compounds from readily available or easily accessible allylic alcohols [2][3][4][5][6]. ...

Since a number of alcohols can be obtained from renewable carbon resources and water is the sole by-product of the reaction, the amination of biomass-derived alcohols to corresponding amines is envisioned as a promising route for transforming amine synthesis into a more sustainable manner [23,28,[35][36][37][38][39][40]. ...
