Title:
HYDROXYMETHYLCROWN AND ITS PREPARATION
Document Type and Number:
Japanese Patent JPS5519222
Kind Code:
A
Abstract:
NEW MATERIAL:N,N'-Dimethylhydroxymethyl-14-crown-N2O2 of formula I.
USE: An intermediate of fixed crown useful as interphase shifting catalyst and agent for capturing heavy metals, which is readily recovered and low toxicity.
PREPARATION: Methylenecrown is hydroborated with a diborane as alkylborane or chloroborane by usual method to form the objective compound of formula I. The compound of formula II is prepared by reaction of 2.2'-[trimethylenebis (methylimino)]diethanol with 3-chloro-2-chloromethyl-1-propene in the presence of a base. The resulting compound of formula I is made to react with a chloro- methylated and crosslinked polystyrene in the presence of a base to give the above fixed crown.
