A highly efficient one-pot procedure for the synthesis of complexes of the type [Ir(COD)(Phox)]X, where Phox is a (chiral) phosphinooxazoline ligand, X = PF6 or B[(3,5-(CF3)2C6H3)]4 (BARF), is developed. Former reported syntheses demanded the isolation of pure ligands by column chromatography, but the ligands tend to adsorb irreversibly on silica. Moreover, the chromatography has to be performed with careful exclusion of air. The present method avoids this difficulties. The yields of the syntheses are comparable with those starting from the pure ligands. The method is also suitable for the preparation of complexes of the type [Rh(COD)(Phox)]BARF and [Rh(Phox)2]BARF.

Terminal Acetylenes

A concise one-pot three-component reaction of organic halides­, terminal acetylenes, and sodium azide provided an efficient route for the synthesis of 1,2,3-triazoles. A variety of 1,2,3-triazoles were prepared in good to excellent yields with green solvent glycerol. This procedure used CuI and diethylamine, which are two easily available reagents as the new catalytic system at room temperature.

Nanofibre sepiolite catalyzed the rapid, clean, and highly efficient synthesis of 2-amino-4H-chromene derivatives by a one-pot, three-component condensation of a series of aldehydes, various enolizable C–H bonds (such as dimedone, α-naphthol, resorcinol, and 4-hydroxy-2H-chromen-2-one), and malononitrile in a mixture of water/ethanol. The present method offers several advantages such as high to excellent yields, short reaction times, mild reaction conditions, simple procedure, use of inexpensive, non-toxic, and naturally available catalyst, easy isolation of the products, and no need for column chromatography. The catalyst could be easily separated from the reaction mixture and can be reused for many consecutive trials without a significant decline in its reactivity.
