A series of potential polidentate ligands were developed. The alkoxyethoxy-phosphorylamines were prepared by phosphorylation of different amines with the appropriate dialkoxyethyl phosphite in a two-phase reaction. The characterization of these compounds was carried out by IR, Mass, and NMR spectroscopy. The properties of these compounds as a chelating agent were investigated by direct UV titration technique.

Continuous flow alcoholysis of dialkyl h-phosphonates with aliphatic alcohols

The continuous flow alcoholysis of dialkyl H-phosphonates by aliphatic alcohols in the absence of a catalyst was elaborated using a microwave (MW) reactor equipped with a flow cell. By the precise control of the reaction conditions, the synthesis could be fine-tuned towards dialkyl H-phosphonates with two different and with two identical alkyl groups. In contrast to the “traditional” batch alcoholysis, flow approaches required shorter reaction times, and the products became available at a larger scale.
METHOD FOR THE MANUFACTURE OF DIALKYLPHOSPHITES

Page/Page column 7, (2010/12/26)
A method for the manufacture of dialkyl phosphites is disclosed wherein a P-O component containing from 1 to 6 P-O-P bonds in the molecule is reacted with an alcohol and a carboxylic acid ester having from 1 to 6 carbon atoms in the alkyl group and from 5 to 20 carbon atoms in the esterifying alkyl group of the ester. The dialkyl phosphites are formed under simultaneous removal by distillation of the carboxylic acid formed.
