Some organomercury, -tin and -lead derivatives of 2,6-dimethyl-4-fluorothiophenol and 2,6-dibromo-4-fluorothiophenol of the general type RpMSAr have been prepared. The fluorine chemical shifts of the compounds realtive to internal fluorobenzene and the 19F SCS values for the corresponding substituents have been determined and discussed in terms of steric hindrance and intramolecular coordination, the
已经制备了一些一般类型为R p MSAr的2,6-二甲基-4-氟代硫代苯酚和2,6-二溴-4-氟代硫代苯酚的有机汞,-锡和-铅衍生物。根据空间位阻和分子内配位,确定并讨论了对内部氟苯有活性的化合物的氟化学位移和相应取代基的19 F SCS值,并与这些方面的有机金属取代基R n MS的行为进行了比较。 SH和CH 3 S组的那些。R n异常低的空间要求在汞,锡和铅的化合物中,已证明了MS基团以及分子内配位强度的不同及其对金属原子受体功率的影响。
