was prepared and converted to the 2,4-di-t-butyl-6-isopropylphenyl-substituted phosphonous dichloride, primary phosphine, diphosphenes, and dithioxophosphorane. The 31P NMR chemical shifts of these compounds are close to those of 2,4-di-t-butyl-6-methylphenyl substituted congeners. © 2001 John Wiley & Sons, Inc. Heteroatom Chem 12:418–423, 2001
2-溴-1,5-二叔丁基-3-异丙基苯的制备和转化为2,4-二-叔丁基-6-异丙基苯基取代的二氯化亚膦、伯膦、二膦和二硫代正膦. 这些化合物的 31P NMR 化学位移与 2,4-二-叔丁基-6-甲基苯基取代的同类物的化学位移接近。© 2001 John Wiley & Sons, Inc. 杂原子化学 12:418–423, 2001
