Metathesis cleavage of an NN bond in benzo[: C] cinnolines and azobenzenes by triply-bonded ditungsten complexes
A metathesis reaction of a WW bond and an NN bond was observed by reacting a W-W triply-bonded W(iii)2 complex, (tBuO)3WW(OtBu)3 (1), with benzo[c]cinnoline derivatives to form biphenyl-linked dinuclear (imido)tungsten complexes 2-4. When azobenzene was used as the substrate, a trans to cis isomerization induced by blue-LED light was essential prior to the metathesis cleavage of the NN bond by the WW bond of (Me2N)2(TfO)WW(OTf)(NMe2)2 (6), affording the corresponding imido-bridged dinuclear tungsten complexes 7-9.
Dual chirality control of palladium(II) complexes bearing tropos biphenyl diamine ligands
Axial and center chirality of Pd complexes with tropos biphenyl secondary diamine ligands is shown to be controlled by chiral amide (R)-DABNTf, which can efficiently discriminate between two enantiomeric Pd complexes. The Royal Society of Chemistry 2005.
