Abstract Cross‐coupling of nitriles and alcohols offers an environmentally friendly atom‐economical method for the synthesis various valuable compounds. These compounds include α ‐alkylated ‐olefinated nitriles, primary amines, imines, N ‐alkylation amides, ‐heterocycles, δ ‐hydroxynitriles, olefins, etc . Herein, we have reviewed recent developments (from 2013–date) transition‐metal‐catalyzed cross‐coupling alcohols. A number transition metal complexes such as noble metals Ru Ir, well base Mn, Fe, Co, Ni are presented. Moreover, different product types, reaction conditions mechanisms discussed to understand catalyst development.

Abstract Herein, we report a straightforward approach for synthesizing C3-alkylated indoles selectively via an iron-catalyzed alkylation of using alcohols as the alkylating agents. A well-defined, air-stable, and easy-to-prepare Fe(II) catalyst redox-active tridentate arylazo scaffold was used catalyst. Various were prepared in moderate to good isolated yields by coupling with different substituted alcohols. The methodology is compatible gram-scale synthesis. Control experiments performed unveil mechanism, which revealed that reaction proceeds borrowing-hydrogen pathway where coordinated azo-aromatic ligand actively participates during catalysis, acting electron hydrogen reservoir.

Herein, we describe a Zn-catalyzed atom-economical, inexpensive, and sustainable method for preparing broad spectrum of substituted olefins utilizing alcohols as the main precursor. Using Zn(II) complex [ZnLCl2] (1) redox-noninnocent ligand 2-((4-chlorophenyl)diazenyl)-1,10-phenanthroline (L), various (E)-olefins were prepared in good yields by coupling with sulfones aryl cyanides under an inert atmosphere. Under aerial atmosphere, vinyl nitriles isolated up to 82% yield reacting benzyl presence 1. Control experiments mechanistic investigation indicate active involvement aryl-azo electron hydrogen reservoir, permitting 1 perform promising catalyst.
