InBr3 Catalyzed intermolecular hydroamination of unactivated alkenes

InBr3 has been demonstrated to be a simple catalyst for the intermolecular hydroamination of unactivated alkenes to produce tosyl- and mesyl-protected amines in moderate to good yields.

Iron-Catalyzed Hydroamination and Hydroetherification of Unactivated Alkenes

The hydrofunctionalization of alkenes, explored for over 100 years, offers the potential for a direct, atom-economical approach to value-added products. While thermodynamically favored, the kinetic barrier to such processes necessitates the use of catalysts to control selectivity and reactivity. Modern variants typically rely on noble metals that require different ligands for each class of hydrofunctionalization, thereby limiting generality. This Letter describes a general iron-based system that catalyzes the hydroamination and hydroetherification of simple unactivated olefins.

Simple and versatile catalytic system for N-alkylation of sulfonamides with various alcohols

"Chemical Equation Presented" A simple and versatile catalytic system for N-alkylation of sulfonamides with various alcohols based on a catalytic hydrogen transfer reaction has been developed under a low catalyst loading of [Cp*lrCl2]2 (0.050-1.5 mol %) in the presence of t-BuOK. A variety of N-alkylated sulfonamides were prepared In good to excellent yields. Mechanistic investigations revealed that the key catalytic species in the present system is a sulfonylimido-bridged unsaturated diirldium complex [(Cp*lr)2(μ-NTs)2].
