PHOSPHONIUM SALT SUPPORTED ON MAGNETIC FINE PARTICLE, METHOD FOR PRODUCING THE SAME, PHASE-TRANSFER CATALYST COMPOSED OF THE PHOSPHONIUM SALT AND SUPPORTED ON MAGNETIC FINE PARTICLE, AND PHASE-TRANSFER REACTION TO USE THE CATALYST

摘要

PROBLEM TO BE SOLVED: To provide a phase-transfer catalyst separable and recoverable by magnetic force and enabling the reuse of the catalyst.;SOLUTION: 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; R¹ is a hydrocarbon group; R², R³ and R⁴ are each a hydrocarbon group and these groups may be bonded together to form a ring; R⁵ is a 1-3C alkyl; and X^- is an anion of an acid.;COPYRIGHT: (C)2008,JPO&INPIT
