Notizen: Tricyclische Phosphorane aus den Phosphonigsäuredichloriden RPCl2 (R = Ph, CH2Ph) und dem (Z)-Ketoenol CF3C(O)CH = C(OH)CF3 / Tricyclic Phosphoranes from the Phosphonous Dichlorides RPCl2 (R = Ph, CH2Ph) and the (Z)-Ketoenol CF3C(O)CH=C(OH)CF3

Abstract

The phosphonous dichlorides, PhPCl2 and PhCH2PCl2, react with the (Z)-ketoenol CF3C(O)CH=C(OH)CF3 to yield tricyclic trialkoxyphosphoranes, whose structures were determined on the basis of the 1JPC values and “through-space” F···F coupling
