Method of synthesis of pi-allyl-palladium compounds

A method of preparing a preselected pi-allyl palladium compound, said method comprising:

• reacting a vinylmercuric halide salt with an olefin of the formula:
• ##STR13## wherein W, Y and Z are selected from the group consisting of aliphatic, alicyclic and aromatic organic radicals and a palladium (II) halide salt to provide carbon-carbon bond formation between carbon atoms of said vinylmercuric halide salt and said olefin, said vinylmercuric halide salt and said olefin being preselected so that after said carbon-carbon bond formation, and complexing with said palladium salt, said preselected pi-allyl-palladium compound is obtained.

A method of preparing pi-allyl-palladium compounds, said method comprising:

• reacting a vinylmercuric halide salt of the formula:
• ##STR14## wherein R and R' are organic radicals selected from the group consisting of hydrogen, alkyl, aryl, aralkyl and X is a halide anion, with an olefin of the formula:
• ##STR15## wherein, W, Y and Z are monovalent organic radicals selected from the group consisting of hydrogen, alkyl, aryl, aralkyl, and with a palladium (II) halide salt, to provide carbon-carbon bond formation between carbon atoms of said vinylmercuric halide salt and said olefin, R, R', W, Y and Z being preselected to represent organic moieties of said pi-allyl-palladium halide.
