N-dimethylaminomethyl)phenyl group was utilized to prepare [4-t-butyl-2,6-bis(N,N-dimethylaminomethyl)phenyl]thioxophosphine sulfide. A 31P NMR chemical shift of the thioxophosphine sulfide shows a high field shift by 153 ppm compared with that of (2,4,6-tri-t-butylphenyl)thioxophosphine sulfide, suggesting a strong intramolecular participation with the lone-pair electrons of the nitrogen atom in stabilization of the
4-叔丁基-2,6-双(N,N-二甲氨基甲基)苯基用于制备[4-叔丁基-2,6-双(N,N-二甲氨基甲基)苯基]硫代膦硫化物。与(2,4,6-三叔丁基苯基)硫代膦硫化物相比,硫代膦硫化物的 31P NMR 化学位移显示出 153 ppm 的高场位移,这表明在分子内具有很强的孤对电子参与氮原子稳定 -P(=S)2 基团。
