Sur quelques diiriviis quaternaires du triaminomiithyle-oxymiithyle-miithane, du 3-aminomiithyle3-bromem6thyle-oxacyclobutane et du 3-3-diaminomiithyle-oxacyclobutane par 1. CAZIER ( I ) et F. GOVAERT SUMMARY.
-Continuing earlier publicatiuns, e here communicate a method of preparation for some quaternary animoniumsalts corresponding with :
1" The triamine derivable from tetramethylmethane;
2 O 3-bromrriethyl-3-aminometh~I-ouacyclol~ut~ii(~; 3' 3-:3-diaminomethyl-oxacyclohutane.
A new w a y for preparing the already dcscribed tetrakistrimrtli>laminomethylmethane ( z ) is also given. This product is formed during the reaction of trimethylamine on tribromas well a5 on dihrom-and monobrompcntaerythritol. However, under the same experinierital conditions, the yields drop from 47 % to 15 % and 2 %, according to the bromderivative used.
