Abstract:
A production process by which tertiary phosphine with an attached sterically bulky hydrocarbon group is produced in a high yield and with high purity on an industrial scale through simple and safe operations by allowing a dialkylphosphinous halide to react with a Grignard reagent in the presence of a copper compound in an amount corresponding to 0.1 to 5% by mol based on the dialkylphosphinous halide to produce tertiary phosphine represented by the following formula (3): wherein R1 and R2 are each a tertiary hydrocarbon group of 4 to 13 carbon atoms, and R3 is an alkyl group, an alkenyl group, an aryl group or the like.

Abstract:
The invention relates to a phosphonium borate compound represented by Formula (I) (hereinafter, the compound (I)). The invention has objects of providing (A) a novel process whereby the compound is produced safely on an industrial scale, by simple reaction operations and in a high yield; (B) a novel compound that is easily handled; and (C) novel use as catalyst. Formula (I): (R1)(R2)(R3)PH.BAr4 (I) wherein R1, R2, R3 and Ar are as defined in the specification. The process (A) includes reacting a phosphine with a) HCl or b) H2SO4 to produce a) a hydrochloride or b) a sulfate; and reacting the salt with a tetraarylborate compound. The compound (B) has for example a secondary or tertiary alkyl group as R1 and is easily handled in air without special attention. The use (C) is characterized in that the compound (I) is used instead of an unstable phosphine compound of a transition metal complex catalyst for catalyzing C—C bond, C—N bond and C—O bond forming reactions and the compound produces an effect that is equal to that achieved by the transition metal complex catalyst.
