  Electrophilic Substitution of 1,1,2,2,9,9,10,10-Octafluoro[2.2]paracyclophane

  摘要：

  Nitration of octafluoro[2.2]paracyclophane (OFP) provides an entry into the synthesis of a series of II monosubstituted OFPs, including the nitro, amino, chloro, bromo, iodo, hydroxy, and trifluoromethyl compounds. The NMR, mass spectrometric, and UV spectral properties of all of these derivatives are presented and discussed, and they are compared with those of its hydrocarbon analogue, [2.2]paracyclophane.

  Complete assignment of the (1)H and (19)F chemical shifts in 4-fluoro-AF4 (1) were based on the nOes seen in its (19)F-(1)H HOESY spectrum. This allowed for identification of features which can further be applied to the assignment of the regiochemistry of substituted perfluoroparacyclophanes (PCPs) and AF4s: (i) an aromatic fluorine couples with the two fluorines in the closest bridge that are syn

  4-氟-AF4（1）中（1）H和（19）F化学位移的完全分配是基于在（19）F-（1）H HOESY光谱中看到的nOes。这可以鉴定特征，这些特征可以进一步应用于取代的全氟对环环烷（PCP）和AF4的区域化学的分配：（i）芳族氟与最接近的桥中与之同位的两个氟偶合，常数为约。20赫兹; （ii）在相同的对亚苯基部分中，芳族氟与桥氟偶合了五个键，该氟与它反键，其常数为约3。3.5赫兹; （iii）桥氟的邻位氟为246 Hz，如果不含邻氟，则为238 Hz；（iv）桥氟与相同的对亚苯基部分中的芳族质子偶合，它们相隔四个或五个键且反。这些特征已被用于分配假邻位，假元和假对二氟AF4 2-4的区域化学。还已经证明，用于桥氟的SCS也可以用于该分配。

  Dehydroiodination of 4-iodo- and 4,15-diiodo-1,1,2,2,9,9,10,10-octafluoro[2.2]paracyclophane by treatment with (KOBu)-Bu-t in the presence of benzene, naphthalene, anthracene, and [2.2]paracyclophane affords each of the corresponding Diels-Alder mono- and bis-cycloadducts derived from the presumed aryne intermediates in high yield. Monoadducts of t-butylbenzene and furan are also obtained in excellent yield. All of the products were characterized by their NMR spectra, with four of them also being confirmed by X-ray crystallography. The extraordinary selectivity/reactivity of the aryne intermediate is discussed.
