NEW MATERIAL:N,N'-Dimethylmethylene-14-crown-N2O2 of formula I.
USE: Starting material for fixed crown compounds, which are useful as interphase shifting catalyst and agent for capaturing heavy metals, the resulting fixed crown catalyst is readily recovered and low toxic. The compound of formula I is subjected to hydroboration to form the hydoxymethyl crown, which is reacted with chloromethylated and crosslinked polystyrene in the presence of a base to produce said fixed crown.
PREPARATION: The reaction of 2,2'-[trimethylenebis(methylimino)]diethanol with 3-chloro-2-chloromethyl-1-propene is conducted to form the objective compound of formula I. The reaction is effected by using equimolr amounts of the starting compounds in an inert solvent as tetrahydrofuran at room temperature. Adiition of a base as sodium hydride is preferred for neutralizing evolving hydrogen chloride.
