“…There was no evidence for the formation of any five-coordinate PtCl 2 (Ar-BIAN)(C 2 H 4 ) complex under the conditions described here. No PtCl 2 (Ar-BIAN) complexes were obtained when Ar-BIAN was reacted with K 2 PtCl 4 , which was used for the synthesis of PtCl 2 (phen), cis - / trans -PtCl 2 (SEt 2 ) 2 , and trans -PtCl 2 (MeCN) 2 …”

The synthesis and characterization of divalent palladium and platinum complexes of the type PdX 2 (Ar-BIAN) (X ) Cl, Br, I, OC(O)Me), PdCl 2 (Ph-BIC) and PtCl 2 (Ar-BIAN) is described. These complexes contain the rigid bidentate nitrogen ligands bis(arylimino)-acenaphthene (Ar-BIAN; Ar ) Ph, p-MeC 6 H 4 , p-MeOC 6 H 4 , o,o′-Me 2 C 6 H 3 , o,o′-i-Pr 2 C 6 H 3 ) or bis(phenylimino)camphane (Ph-BIC), which act as σ-donor ligands to the metal center, as was deduced from the observed shifts in the IR and NMR spectra of the complexes. IntroductionDivalent palladium and platinum complexes are valuable catalyst precursors and have been used in a wide variety of reactions, including carbonylation of alkenes, organic halides, and nitroaromatic compounds, 2 C-C cross coupling, 3 allylic alkylation, 4 and Heck type reactions. 5 A general feature of most of these reactions is the in situ reduction of the catalyst precursor, leading to a formal 14-electron zerovalent complex which undergoes oxidative addition of one of the reacting substrates. In situ reduction of Pd(II) precursors by Al(iBu) 2 H 3h or Li 2 (cyclooctatetraene) 6 prior to further reactions has been reported. The formation of a Pd(0) complex from the Pd(OC(O)Me) 2 /PPh 3 system has been elucidated by electrochemistry. 7 We have recently demonstrated the activity of divalent palladium complexes containing the rigid bidentate nitrogen ligands bis(arylimino)acenaphthene (Ar-BIAN) in catalytic cross coupling reactions of organic halides with organomagnesium and -zinc compounds, whereas similar reactions employing organotin reagents were more effectively catalyzed by zerovalent complexes of the type Pd(Ar-BIAN)(alkene). 8 ...
