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.
本发明涉及一种由式(I)表示的硼酸鏻化合物(以下简称化合物(I))。本发明的目的是:(A)提供一种新的工艺,通过简单的反应操作和高产率,在工业规模上安全地生产该化合物;(B)提供一种易于处理的新化合物;(C)提供作为催化剂的新用途。
式 (I) : (R1)(R2)(R3)PH-BAr4 (I)
其中 R1、R2、R3 和 Ar 如说明书中所定义。
工艺 (A) 包括将膦与 a) HCl 或 b) H2SO4 反应生成 a) 盐酸盐或 b) 硫酸盐;并将该盐与四芳基硼酸盐化合物反应。
化合物(B)的 R1 例如是仲烷基或叔烷基,在空气中容易处理,无需特别注意。
