Cd(II)-tetrakis compoundX-ray structureImidazolyl and 3 ′-pyridyl are linked by azo bond (–N N–) to synthesize hitherto unknown mixed heterocyclic azo molecules, 2-[(3 ′-pyridyl)azo]imidazole (3 ′-PyaiH). Alkylation in presence of NaH has synthesized 1-alkyl-2-[(3 ′-pyridyl)...
In this work, we present an innovative approach to investigate the structure and the reactivity of a molecularly dispersed organometallic compound. The poly(4-ethylstyrene-co-divinylbenzene) microporous system (PS) is used as "solid solvent" able to molecularly disperse CrCp2, allowing: (i) its...
