Employing green and economic solvent-free synthesis route, hexagonal iron sulfide (Fe7Ss) nanoflowers were successfully synthesized for the first time. In the experiment, ferric hexadecylxanthate was used as the pre...
A direct and efficient approach to 1-aminoindolizines through three-component one-pot reaction of heteroaryl aldehydes, secondary amines and terminal alkynes catalyzed by CuI under solvent-free conditions has been dev...

A new approach to synthesize N-alkylation of azoles by iron(III)-catalyst under solvent-free conditions was de- veloped. The method is broad in scope and highly efficient.
Aromatic ketones are directly alkylated at a position with primary alcohols at 110 ℃ in the presence of catalytic amount of KOH and [Cp*lrC12]2 (Cp*=pentamethylcyclopentadienyl) catalyst. The reaction is carried ...
Quaternary ammonium bases, such as aqueous (CH3)4NOH, were found to be an extraordinarily efficient cata-lyst for cyanosilylation of aldehydes. The addition reaction of trimethylsilyl cyanide (TMSCN) to equivalent...
This paper reports a practical and green method for the acetalization of carbonyl compounds as pentaerythritol diacetals and diketals derivatives using cellulose sulfuric acid as a biodegradable and reusable solid aci...
