Abstract
For the phosphonamidic chloride R(2)CHP(O)(NEt(2))Cl having R(2)CH = 9 -fluorenyl, substitution at phosphorus is unexpectedly fast with Et(2) NH as the nucleophile, and discriminates less than is usual between co mpeting Me(2)NH and Et(2)NH nucleophiles; such behaviour is consistent with an elimination-addition mechanism and a fluorenylidineoxophospho rane intermediate 8.
