equilibrium constants are reported. Bidentate phosphine and phosphinoarsine simultaneously split the bridge and cleave the Pd–N(azo) bond. Anhydrous HCI gas protonates the oximato-group with its concomitant displacement by Cl– ion; in effect the Pd–N(oxime) bond is selectively cleaved.

because this process lengthens the DNA helix due to the increased separation of the DNAbase pairs when the compound slides in between, whereas a partial, nonclassical intercalation could bend (or kink) the DNA helix, which leads to a reduction in length and thereby reducing its viscosity. By contrast, there will be no change in the viscosity when the compounds bind with DNA grooves or by partial intercalation
that the triphenylarsine ligand can accelerate the reaction rate of Stille coupling. However, other arsine ligands have never been investigated for the Stille coupling reaction so far. In this work, we prepared 13 kinds of C3-symmetrical tertiary arsine ligands and discovered that tri(p-anisyl)arsine is the best ligand for the reaction of tributylvinyltin and p-iodoanisole. The reaction mechanism was

AuClL(1)/PdCl2L(2)2 cocatalyzed coupling of Ar(1)X and Ar(2)SnBu3 is feasible for bulky Ar(1), provided that at least one ligand on Pd is not strongly coordinating. This can be achieved in situ by Au/Pd ligand exchange if L(1) is weakly coordinating. When the exchange is slow, independent preparation of appropriate catalysts is recommended.
the enol form in all the complexes. The structural analysis of 2 and 3 confirms the square planar geometry of the two complexes. The DNA binding of these complexes and ligand calf thymus DNA (CT-DNA) was investigated by using various methods, which revealed that the compounds interacted with CT-DNA through intercalation.
