2,2-Diorganyl-6-(O,O-diethylphosphonomethyl)-1,3-dioxa-6-aza-2-silacyclooctanes and 0,0-diethyl-phosphonomethylbis(2-trimethylsiloxyethyl)amine

The reaction of O,O-diethylphosphonomethylbis(2-hydroxyethyl)amine with dialkylbis(di-ethylamino)silanes and hexamethyldisilazane leads to 2,2-dialkyl-6-(O,O-diethylphosphono-methyl)-1,3-dioxa-6-aza-2-silacyclooctanes and O,O-diethylphosphonomethylbis(2-trimethyl-silyloxyethyl)amines, respectively.
