“…Simultaneously, our research also extended to another green oxidant: H 2 O 2 . In 2017, we demonstrated a highly innovative and convenient palladium‐catalyzed oxidative amination of amines with vinyl esters, and plentiful functionalized α‐amino acid esters (Scheme ) . Notably, 18 O‐labeling experiments suggested that H 2 O 2 acted as a green oxidant and oxygen source (Scheme ).…”

Transition‐metal‐catalyzed oxidative functionalization of alkenes has emerged as a powerful and valuable tool in modern organic synthesis. Recently, many methods have been established for the assembly of C−C and C–heteroatom bonds, which provides tremendous possibility for application in biology, medicine, and materials science. However, the use of stoichiometric amounts of strong oxidants leads to poor selectivity, low atom economy, and a series of undesired waste products. By contrast, green oxidants, such as O2, H2O2, or tert‐butyl hydroperoxide (TBHP), have bright prospects due to their attributes of mild, low cost, and great sustainability in transition‐metal‐catalyzed oxidation reactions. Based on the great and unique potential for the development of aerobic reactions, this review mainly highlights homogenous palladium‐catalyzed green oxidations of alkenes that have been reported in recent years. These methods provide new strategies for the transformation and functionalization of alkenes; some of them have also been successfully applied to the synthesis of the core structures of drugs and natural products. Additionally, through in‐depth studies of the reaction mechanisms in this field, it is believed that palladium‐catalyzed green oxidation reactions of alkenes with O2, H2O2, or TBHP will create added value for organic synthetic chemistry.

The synthesis of aromatic amines is of continuous interest in chemistry. An exceptionally versatile three‐component reaction that directly transforms inexpensive nitro compounds, boronic acids, and trialkyl phosphites into tertiary aromatic amines has been realized. The reaction tolerates alkyl and aryl substituents on the nitro and boronic acid moieties, as well as functionalized phosphites. No transition‐metal catalysis is required. The method is orthogonal to other classical metal‐catalyzed syntheses since it tolerates the presence of halogens, and also permits the synthesis of functionalized compounds such as α‐amino ester derivatives.
