Abstract
Abstract WHEREIN: X is the same or different element selected from nitrogen or oxygen; Y is the same or different element selected from oxygen, sulfur or nitrogen and nitrogen when both X''s are oxygen; R is a hydrocarbylene or dihydrocarbylene having from 2 to 18 carbon atoms; R1 is the same of different hydrogen or a hydrocarbyl having from 1 to 24 carbons; R2 is the same or different R1 or a hydrocarbylene having from 2 to 18 carbon atoms with one end of each R2 bonding to the other R2 or to said R dihydrocarbylene; N IS 1 WHEN Y is oxygen or sulfur and 2 when Y is nitrogen; and M IS N-1. Novel bisphosphoramides are prepared by reacting phosphorus oxychloride with a difunctional compound and a monofunctional compound within a liquid phase reaction medium to produce compounds having the structure:
