series of 3,4-disubstituted (4a, b) or 3,4-fused (4c-e) 1,1-di-fluorocyclopropabenzenes, including the very strained 1,1-difluoro-3,4-dihydro-1 H-cyclobuta[a]cyclopropa[d]benzene (4e) have been synthesized and characterized. Dissolution of these difluoro derivatives in fluorosulfonic acid affords the fluoro cations 3a–e. 1H-, 19F-, and 13C-NMR data of the cations are reported and discussed with respect
一系列3,4-二取代(4a,b)或3,4-稠合(4c - e)1,1-二氟环丙苯,包括非常紧张的1,1-二氟-3,4-二氢-1 H合成并表征了-cyclobuta [ a ] cyclopropa [ d ]苯(4e)。这些二氟衍生物在氟磺酸中的溶解提供了氟阳离子3a – e。报告并讨论了关于前体的阳离子的1 H-,19 F-和13 C-NMR数据。
