Conclusions
-
1.
Di(phenylaminomethyl)phenylphosphine, N,N-disubstituted-5-phenyl-1,3,5-diazaphosphorinanes, and 1,5-diaza-3, 7-diphosphacyclooctane, on treatment with excess alkyl halide, are alkylated only at the P atom. In the case of bis(diethylaminomethyl)phenylphosphine, addition occurs at both phosphorus and nitrogen.
-
2.
Reaction of 1,3-di-p-tolyl-5-tolylaminomethyl-1,3,5-diazaphosphorinane with alkyl halides affords P alkylation products with one and two moles of alkylating agent.
