Abstract: A process for preparing tetrakis (pentafluorophenyl) borate is described that involves reaction of a pentafluorophenyl magnesium halide with an alkali metal tetrafluoroborate.

Abstract: A method for the production of tetrachloropalladic acid and bis(acetonitrile) palladium dichloride is described. Palladium metal is reacted with concentrated hydrochloric acid and chlorine to produce the acid which is converted to bis(acetonitrile) palladium dichloride by reaction with acetonitrile.

Abstract: Procedures are disclosed which preclude significant safety hazards in the production of bulk quantities pentafluorophenyl lithium. A pentafluorophenyl compound is reacted with an alkyl lithium compound in a reaction zone, preferably temperature controlled, under conditions such that only a small amount of a predetermined quantity of pentafluorophenyl lithium product is present in the reaction zone at any time. The product may be directly discharged from the reaction zone for combination with another reactant.

Abstract: A method for making diphenyl carbonate free of color bodies is provided by reacting an organic hydroxy compound, such as phenol with carbon monoxide and oxygen in the presence of an effective amount of a palladium catalyst, in the form of a palladium material which is used in combination with a quaternary ammonium salt, an inorganic cocatalyst, such as cobalt diacetate and an organic cocatalyst such as benzophenone or 1,10-phenanthroline. Recycling of catalyst values is also provided.

Abstract: Silicon hydrides substituted with oxygen containing radicals such as alkoxy, can be silylformylated with alkynes and carbon monoxide in the presence of a rhodium catalyst to produce silyl alkenyl acetals. The silyl alkenyl acetals are useful as plasticizers for organosilicon copolymers.

Abstract: An improved method for making biaryl compounds is disclosed, in which an aromatic acid halide having at least one strong electron-withdrawing group attached to or within the aromatic ring is reacted with at least one polysilane in the presence of an effective amount of a transition metal catalyst.

Abstract: A method is provided for silylating aromatic acylhalide by effecting reaction between an aromatic acylhalide and halogenated polysilane in the presence of an effective amount of a supported transition metal catalyst, such as a transition metal catalyst supported by an organic or inorganic substrate.

Abstract: A complex of a tetradentate tetraanionic ligand L of the formula: ##STR1## and a metal, preferably a transition metal, is described where Z is an anionic oxidation reistant metal complexing group, Ch is an oxidation resistant chelate group containing 1 to 4 chain atoms and Y is hydrogen. The chelate and ring Z-Ch-M-Z functional groups Z, such as N or O, are resistant to oxidation and the ring contains 4 to 7 preferably 5 to 6 chain atoms. An osmium complex containing two pyridine ligands is an oxidation catalyst. Further activation by anodic oxidation and heating to a temperature exceeding 30.degree. C. greatly increases catalytic activity.
