Reactivity of chiral diiminodiphosphine ligands towards PdCl2(PhCN)2: synthesis and crystal structures of two unexpected dinuclear palladium(II) complexes
Abstract
The interaction of PdCl2(PhCN)2 with (S)-N,N′-bis[2-(diphenylphosphino)benzylidene]-2,2′-diimino-1,1′-binaphthylene (S)-L1 and (S,S′)-N,N′-bis[2-(diphenylphosphino)-benzylidene]-1,2-diimino-1,2-diphenylethane (S,S′)-L2 gave the dimeric complex {PdCl[2-(Ph2P)C6H4CHN]}21 and the dinuclear complex {cis-PdCl2[2-(Ph2P)C6H4CH NCH(Ph)CH(C6H4PPh2-2)NC6H4(PPh2)-2]PdCl}{Cl}
2, respectively, whose structures were ascertained by
