Stability, molecular structures and magnetic properties of dinuclear iron complexes supported by benzoic hydrazide derivative ligands
摘要:
We report experimental evidences including molecular solid-state structure determinations, magnetic measurements and EPR studies for the formation (in the solid-state) of novel dinuclear Fe-2(III)(mu-OMe)(2)(L)(4) complexes (HL are 2-ylidenhydrazidebenzoic-1,3-dithiolane acid and N'-cyclopentylidene-2-hydroxybenzohydrazide). The two novel dinuclear iron compounds described in the present contribution exhibit antiferromagnetic intra-molecular coupling. Crystal structures of the supporting ligands as well as one mononuclear species have also been determined. (C) 2009 Elsevier B. V. All rights reserved.
Fast Synthesis of N-Acylhydrazones Employing a Microwave Assisted Neat Protocol
摘要:
A variety of N-acylhydrazones were synthesized Under microwave irradiation within 2.5-10 min, starting from benzo, salicyloyl, and isonicotinic hydrazides. The protocol developed employs microwave irradiation in the absence of solvents and catalysts, leading to high yields. The results are reproducible in a 500 mg to 5 g scale.
