磁性微粒子に担持したホスホニウム塩とその製造方法、及び該ホスホニウム塩からなる磁性微粒子担持相間移動触媒並びにそれを用いた相間移動反応

Document Type and Number:

Japanese Patent JP4986117

Kind Code:

B2

Abstract:

To provide a phase-transfer catalyst separable and recoverable by magnetic force and enabling the reuse of the catalyst.

A phosphonium salt supported on a magnetic fine particle, expressed by the figure and separable and recoverable by a magnet is used as a phase-transfer catalyst. In the formula, M is the magnetic fine particle; R1is a hydrocarbon group; R2, R3and R4are each a hydrocarbon group and these groups may be bonded together to form a ring; R5is a 1-3C alkyl; and X-is an anion of an acid.
