Conclusions
-
1.
A study was made of the reaction of alkyl hypophosphites with bis(diethylamino)methane and diethylaminomethyl ethyl ether. A number of esters of bis(α-aminomethyl)phosphonic acids was obtained.
-
2.
Bis(α-aminomethyl)phosphonic acids are obtained in the case of the alkyl hypophosphites where the alkyl radical contains more than 6 C atoms. The alkyl hypophosphites with smaller radicals give either the esters ofα-aminomethylphosphonic acids or a mixture of the latter with the esters of bis (α-aminomethyl)phosphonic acids.
