Hydroaminomethylation (HAM) is one of the most promising atom-economic processes for production secondary amines, which so far remains extremely challenging with anilines as substrates. Herein, we report use combined micellar and microwave catalysis HAM olefins in water reaction medium that allows synthesis good yields high regioselectivities. For rhodium/xantphos catalyst system, mechanistic investigations suggest a pathway different to commonly observed mechanisms homogeneous catalysts reported reaction, involving carbonylation initiated by C–H activation rather than classical hydroformylation steps.

Comprehensive Summary Since the discovery of hydroformylation (oxo‐synthesis or Roelen reaction) and Reppe‐reaction, transition metal‐catalyzed carbonylation reactions, providing versatile, facile, even atom‐economic methods for selective incorporation C=O functionality to various skeletons, have gained tremendous importance in synthetic organic chemistry from laboratories industrial applications. The carbon‐carbon multiple bonds, aromatic halides, triflates, etc ., presence nucleophiles has led way produce aldehydes, carboxylic acids, esters, amides, fine chemical industry. However, these protocols usually proceed conventional, fossil‐based, toxic reaction environments. Thus, several attempts been directed developing efficient alternative, less harmful, non‐fossil‐based renewable media. In this review, we overview recent applications alternative solvents such as water, biomass‐based alcohols, γ‐valerolactone (GVL), 2‐methyltetrahydrofuran (2‐MeTHF), ionic liquids (ILs), deep eutectic (DES), alkyl levulinates, limonene, α‐pinene, dimethyl carbonate well fluorous media improve efficiency, safety environmentally benign nature protocols.

Organophosphorus ligands are an invaluable family of compounds that continue to underpin important roles in disciplines such as coordination chemistry and catalysis. Their success can routinely be traced back facile tuneability thus enabling a high degree control over, for example, electronic steric properties. Diphosphines, phosphorus bearing two separated PIII donor atoms, also highly valued impart their own unique features, example excellent chelating properties upon metal complexation. In many classical this type, the backbone connectivity has been based on all carbon spacers only but there is growing interest embedding other atoms additional nitrogen (–NH–, –NR–) sites.
