Friedel-Crafts alkylation of indoles with nitroalkenes catalyzed by a novel Zn（II）-thiourea complex has been developed. The remarkable advantages of this reaction are mild reaction conditions, simple workup procedure, high yield of products and the use of ethanol as acceptable solvent.
Co（ClO_4））_2·6H_2O/bis-Schiff base complexes promoted the conjugate addition of indole toα,β-unsaturated ketones under mild conditions,giving the corresponding addition products with high yields.And the complex has been characterized with XRD and IR.
CrCl3·6H2O/hydrogenated bis-Schiff base is found to be an effective catalyst system for synthesis of bis（indoly） methane via electrophilic addition reaction of indoles with aldehydes using acetonitrile as the solvent. The yields of isolated products are from good to excellent.
A series of new ligands L_1-L_7 were readily prepared in one step.Friedel-Crafts alkylation of indoles with nitroalkenes catalyzed by a novel Cu（Ⅱ）-L complex has been developed.The remarkable advantages of this reaction are mild reaction conditions,simple workup procedure,high yields of products and the use of ethanol as a green solvent.

A series of novel Schiff bases bearing triazole structure were synthesized and characterized by LR and NMR. Mn（OAc）2/Schiff base efficiently catalyzed Henry reaction of nitroalkanes with aldehydes to produce the corresponding products of ^-nitroalcohols, under mild conditions with high yields （up to 99%）. A reaction mechanism is proposed based on the experimental results.
