摘要： Pentafluorophenylmagnesium halides are prepared by a Grignard exchange reaction of hydrocarbylmagnesium halide with pentafluorochlorobenzene. The pentafluorophenylmagnesium halides are converted to pentafluorophenyl metal or metalloid derivatives by reacting them with metal or metalloid halides such as BF.sub.3.

摘要： Fluoroaryl Grignard reagents are produced from a hydrocarbyl Grignard reagent and fluoroaromatic compounds via separate additions of different fluoroaromatic compounds, such that the conversion of hydrocarbyl Grignard reagent to the desired fluoroaryl Grignard reagent is essentially complete, and thus the reaction product is free or essentially free of agents that may negatively affect subsequent reactions. The fluoroaryl Grignard reagents may be further reacted with boron trihalides in order to obtain tris(fluoroaryl)boranes or tetrakis(fluoroaryl)borates.

摘要： A slurry is formed from an auxiliary catalyst (e.g., an aluminoxane or organoboron compound), a porous inorganic oxide carrier, and an inert organic solvent. The slurry is enclosed in a closed vessel and the temperature and pressure of the enclosed slurry are increased to a temperature of from about 80.degree. C. to 250.degree. C. and a pressure of from about 5 to 500 psig such that a supported composition is produced in the vessel. After opening the closed vessel, the supported composition and the solvent are separated from each other.

摘要： Perfluoroaryl Grignard reagents are produced from a hydrocarbyl Grignard reagent and polyhaloaromatic compounds via separate additions of different polyhaloaromatic compounds, such that the conversion of hydrocarbyl Grignard reagent to the desired perfluoroaryl Grignard reagent is essentially complete, and thus the reaction product is free or essentially free of agents that may negatively affect subsequent reactions. The perfluoroaryl Grignard reagents may be further reacted with boron trihalides in order to obtain tris(perfluoroaryl)boranes or tetrakis(perfluoroaryl)borates.

摘要： A process is described which comprises heating a methylalumoxane solution in an aromatic hydrocarbon solvent at a temperature of at least 35.degree. C. for at least 0.5 hour in an inert, dry atmosphere such that the resulting heat-treated composition provides, in a supported metallocene catalyst produced using the heat-treated composition, increased activity as compared to the same supported metallocene catalyst produced in the same way except for using a portion of the methylalumoxane solution that has not been heat-treated. Before the heating the methylalumoxane of the solution contains from about 5 to about 35 mole percent unreacted trimethylaluminum, and was formed by partial hydrolysis of trimethylaluminum with free water in an organic solvent.
