At the outset, it was by no means certain that these would react efficiently with substituted silylketenes \CN{1} since it is well documented that nucleophiles attack silylketenes \textit{anti} to the silicon, i.e.\ the phosphoranes would be approaching from the same side as the \chem{R^1}-substituent.
