Abstract
Novel ternary salts of tris(aminomethyl)phosphines and their oxides having the formula (R.sub.2 NH.sup.+ CH.sub.2).sub.3 P(O).sub.n 3X.sup.-, wherein R is hydrogen, an alkyl radical having from 1 to 6 carbon atoms or an aryl radical, n is an integer from 0 to 1, and X is a halogen, are prepared by the reaction of a hydrohalic acid, HX, with various nitrogen- and phosphorus-containing compounds including tris(aminomethyl)phosphines and their oxides, tris(N-carbalkoxylaminomethyl)phosphines oxides, and 1,3,5-triaza-7-phosphaadamantane and its 7-oxide.
Claims3
A process for preparing ternary salts of tris(aminomethyl)phosphine and its oxide which comprises hydrolyzing a compound selected from 1,3,5-triaza-7-phosphaadamantane and its 7-oxide having the formula;
- ##STR4## wherein n is an integer from 0 to 1, with three or more parts of a hydrohalic acid, HX, where X is a halogen, until all three of the N--CH.sub.2 N bonds are cleaved, and recovering the product therefrom.
