The invention relates to novel phosphonium borate compounds represented by the Formula: (R)(R)(R)PH.BAr, wherein R, R, Rand Arare as defined herein, and compositions including such phosphonium borate compounds in combination with a transition metal, transition metal salt, transition metal oxide or transition metal complex for use in carbon-carbon bond forming reactions, carbon-nitrogen bond forming reactions and carbon-oxygen bond forming reactions.

Process for producing phosphonium borate compound, novel phosphonium borate compound, and method of using the same

A silane containing a bulky hydrocarbon group or groups R therein and having the formula (III)R(R)(R)Si(OR)can be produced by reacting a silane of the formula (I)(R)(R)SiCl(OR)with a Grignard reagent of the formula (II)RMgXFurther, a tri-organo-chlorosilane of the formula (XIIa)(R)(R)(R)SiClcan be produced by reacting a tri-organo-silane of the formula (XIa)(R)(R)(R)SiZwith hydrochloric acid. Furthermore, a tri-organo-monoalkoxysilane of the formula (XXIII)R(R)(R)Si(OR)can be produced when a silane of the formula (XXI)(R)(R)SiClis reacted with a Grignard reagent of the formula (XXII)RMgXwith addition of and reaction with an alcohol or an epoxy compound during the reaction.

Processes for the production of tri-organo-monoalkoxysilanes and process for the production of tri-organo-monochlorosilanes

The invention relates to methods for carbon-carbon bond forming reactions, carbon-nitrogen bond forming reactions and/or carbon-oxygen bond forming reactions using phosphonium borate compounds represented by the Formula: (R)(R)(R)PH.BAr, wherein R, R, R, and Arare as defined herein in combination with a transition metal, transition metal salt, transition metal oxide or transition metal complex.
