Abstract
N-nitrosoureas which are readily accessible from the reaction of urea derivatives with sodium nitrite and aqueous H2SO4 reacted with acetylenic esters in the presence of Ph3P in ethyl acetate at ambient pressure to give stable phosphorus ylides. This methodology is introduced as a simple and inexpensive procedure for the preparation of organophosphorus compounds in excellent yields.
