streamlined and simplified synthetic route to double carbohelicenes starting from nitroarenes through sequential nitro-activated ortho-C–H arylation, denitrative alkenylation and intramolecular cyclodehydrogenation. In this synthetic strategy, the nitro group plays a dual role namely as a leaving group for the denitrative alkenylation and as an activating group for ortho-C–H arylation, which is distinct

measured the Larmor frequency ω/2π (= 8.50, 22.5, and 53.0 MHz) and temperature T (110–310 K) dependence of the proton spin–lattice relaxation rate R in the polycrystalline solid [low-frequency solidstatenuclear magnetic resonance (NMR) relaxometry]. We have also determined the molecular and crystal structure in a single crystal of 3-t-butylchrysene using x-ray diffraction, which indicates the presence
我们合成了 3-叔丁基苯并测量了多晶固体中质子自旋晶格弛豫速率 R 的拉莫尔频率 ω/2π(= 8.50、22.5 和 53.0 MHz)和温度 T(110-310 K)依赖性 [低频固态核磁共振 (NMR) 弛豫测量法]。我们还使用 X 射线衍射确定了 3-叔丁基单晶中的分子和晶体结构,这表明存在独特的叔丁基环境。由于自旋-自旋偶极相互作用受到叔丁基及其组成甲基的叠加重新定向的调节,自旋 1/2 质子松弛。重新定向通过最简单的运动成功建模;泊松统计描述的随机跳跃。X 射线数据表明近乎镜面对称,其中一个甲基基团几乎位于芳族平面中,而另外两个甲基基团几乎位于该平面的上方和下方。核磁共振弛豫测量数据表明,几乎在...
