• in their dry state. In addition, the method also facilitated short reaction times and provided high yields (Scheme 3). A number of other methods have been developed for the green synthesis of azo compounds [6][7][8][9][10][11][12][13][14][15][16]. Thus far, the above examples concentrate on modifying

• by comparison with analogues ruthenium complexes with unsubstituted or 4′-phenyl-substituted terpyridine. In this contribution we report on the green synthesis and physicochemical investigations of the 4′-azulenyl-substituted terpyridines with particular interest on the fluorescence properties. The

• environmentally hazardous residues and undesirable byproducts [25][26][27][28][29][30]. As one part of our continuing efforts toward the development of green synthesis methods for Michael additions of nitroalkenes, we have previously reported an enzymatic tandem reaction to form 5-hydroxyimino-4,5-dihydrofurans
