Synthesis and characterization of a Sulfonyl- and iminophosphoryl-functionalized methanide and methandiide
- The synthesis of \([H_{2}C(PPh_{2}=NSiMe_{3})(SO_{2}Ph)]\) (\(\bf 1\)) and its mono- and dimetalation are reported. Due to the strong anion-stabilizing abilities of the iminophosphoryl and the sulfonyl group monometalation to \(\textbf {1-K}\) and dimetalation to \(\textbf {1-Li}\)\(_{2}\) proceed smoothly with potassium hydride and methyllithium, respectively. Both compounds could be isolated in high yields and were characterized by NMR spectroscopy as well as XRD analysis. The methanide \(\textbf {1-K}\) forms a coordination polymer in the solid state, while in case of the methandiide a tetrameric structure is observed. The latter features an unusual structural motif consisting of two \((SO_{2}Li)_{2}\) eight-membered rings, which are connected with each other via the methandiide carbon atoms and additional lithium atoms. With increasing metalation a contraction of the P–C–S linkage is observed, which is well in line with the increased charge at the central carbon atom and involved electrostatic interactions.
