Reductive decomplexation, palladium complexes

Nickel and palladium complexes also catalyze the formation of the carbon-phosphorus bonds in phosphorus(V) and phosphorus(III) compounds. Indeed, this chemistry has become a common way to prepare phosphine ligands by the catalytic formation of phosphine oxides and subsequent reduction, by the formation of phosphine boranes and subsequent decomplexation, or by the formation of phosphines directly. The catalytic formation of both aryl and vinyl carbon phosphorus bonds has been accomplished. 

Norbornadiene complexes of platinum and palladium react with silver carboxylates to form the carboxymetallation products 29 which upon treatment with triphenylphosphane undergo intramolecular alkene insertion into the metal-alkyl bond to form nortricyclene 30. Reductive decomplexation leads to acylated nortricyclenol 31 (exu-tricyclo[2.2.1.0 ]heptan-3-ol). ... 

Partial reduction of dichloro(norbomadiene)palladium with sodium borohydride at — 40 C gave an intermediate 25 which could not be isolated but was assumed to be a homoallyl complex which upon reductive cleavage gave norbornene, norbomane and nortricyclene in a ratio of 9 7 1, while oxidative decomplexation gave norbornenone and nortricyclenone in a 1 1 ratio. ...
