Reaction of Elemental (White) Phosphorus with (Alkoxymethyl)dialkylamines
摘要:
The reaction of elemental (white) phosphorus with (alkoxymethyl)dialkylamines in the presence of sodium alkoxide results in complete conversion of P-4 in proton-donor solvents only. P-31 NMR spectroscopy allowed detection of the initial formation of P-III compounds whose subsequent transformations primarily provide phosphinate and phosphonate structures. Under the reaction conditions, trialkyl phosphites further react with (alkoxymethyl)dialkylamines to form dialkyl (dialkylamino)methylphosphonates.
