PROCESS FOR PRODUCING PHOSPHONIUM BORATE COMPOUND, NOVEL PHOSPHONIUM BORATE COMPOUND, AND METHOD OF USING THE SAME |
摘要 |
<p>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. €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒFormula (I) : (R 1 )(R 2 )(R 3 )PH·BAr 4 €ƒ€ƒ€ƒ€ƒ€ƒ(I) wherein R 1 , R 2 , R 3 and Ar are as defined in the specification. The process (A) includes reacting a phosphine with a) HCl or b) H 2 SO 4 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 R 1 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.</p> |
