The reaction of pentaoxyphosphoranes with acetonitrile to give oxazolines

Reactions of phosphite esters and trisdialkylaminophosphines with 5‐substituted 1,3,4‐thiadiazol derivatives

“…The reactions of 1a with trisdialkylaminophosphines (3a,b) were also investigated to determine the mode of addition, as each hexaalkylphosphorustriamide (HAPT) possesses a greater nucleophilicty than the trialkyl phosphites [17,18].…”
