Palladium compounds chemistry

Although complexes with these ligands are common in palladium(II) chemistry, their occurrence is more scarce in platinum(II) compounds. Nevertheless these complexes can be prepared, examples being platinum(II) complexes of the optically active quadridentate Schiff base of salicylaldehyde and (R)-l, 2-diamines.1212 An alternative synthesis involves formation of the Schiff base by reaction of a complexed amino ligand on platinum(II) with amide acetates (equation 372).1213...

The palladium-catalyzed formation of diarylamines has been used in several contexts to form molecules of biological relevance. The ability to prepare haloarenes selectively by an ortfio-metalation-halogenation sequence allows the selective delivery of an amino group to a substituted aromatic structure. Snieckus has used directed metalation to form aryl halides that were subsequently allowed to react with anilines to form diarylamines (Eq. (34)) [209]. Frost and Mendonqa have reported an iterative strategy to prepare, by the palladium-catalyzed chemistry, amides and sulfonamides that may act as peptidomimetics. Diaryl-amine units were constructed using the DPPF-ligated palladium catalysts, and the products were then acylated or sulfonated with 4-bromobenzoyl or arylsulfonyl chlorides [210]. Le-miere has coupled primary arylamines with 4-chloro-3(2H)-pyridazinones to form compounds with possible analgesic and antiinflammatory properties.

Transition-metal catalyzed reactions are now common and attractive routes to exotic indoles with substitution patterns which are otherwise difficult to realize. Using an intramolecular Heck reaction, the precursors 94 were converted to a number of 3-aryl-3-alkenyl oxindoles 95 in good yield and with good ee. The requisite compounds 94 are available in three steps from IV-benzylbenzoxazolin-2-one using palladium-based chemistry <03JA6261>. 

Many organotin reactions are catalysed by platinum or palladium compounds, and this has stimulated interest in compounds containing an Sn-Pt or Sn-Pd bond. The chemistry of the SnPt compounds is much the more thoroughly developed, and, if complexes... 

Recently, the chemistry of ruthenium complexes has been extensively explored. However, they have so far found less application in organic synthesis than palladium compounds, probably because their chemistry is more complicated [99]. Indeed, in contrast to palladium(II) compounds, ruthenium complexes generally have 5- or 6-coordinated geometry and their oxidation state can vary between -2 to 6. This complexity, however, leads to many interesting reactions and further developments in this field are expected. 

The important stabilizing effect of the palladated 8-methyIquinoline ligand [hereafter the Pd compounds derived from this ligand are referred to as Pd(8-mq) has been used to build an original chemistry on the positions trans to it. Thus it is possible to isolate phosphoenolates, when functionalized phosphines are bound to palladium, by direet reaction of a lithium phosphoenolate on the palladium compound , the nuclearity of the product depending upon the stoichiometry ...
