描述了在sp 3碳中心上用全氟烷基格氏试剂进行亲核取代的第一个例子。因此,由全氟化烷基碘化物R F -I制备的一系列有机金属R F -MgBr,其中R F = C 4 F 9,C 6 F 13,C 8 F 17,C 10 F 21和C 12 F 25与1,3,2-二氧杂硫杂环戊烷-2,2-二氧化物反应,得到相应的2-(全氟烷基)乙基硫酸镁,复分解后分离为相应的钾盐。在模型反应中,使全氟己基碘化镁与三氟甲磺酸甲酯反应,生成多氟化烷烃。由于其反应性较差,将反应扩展至1,3,2-二氧杂蒽-2,2-二氧化物的尝试失败,并且在反应混合物中仅检测到还原的多氟烷烃和偶联产物。多氟硫酸盐很容易用盐酸或三氟甲磺酸水解成相应的醇,这是将全氟烷基碘标准转化为2-(全氟烷基)乙醇的一种选择。

The objective of the invention is to provide a polycyclic aromatic compound in which solubility to a solvent, film formability, wet coatability, thermal stability, and in-plane orientation are improved. This objective is achieved by a light emission layer-forming composition comprising: as a first component, at least one type of dopant material selected from the group consisting of polycyclic aromatic compounds represented by general formula (A) and polycyclic aromatic oligomer compounds including a plurality of structures represented by general formula (A); as a second component, a specific low-molecular-weight host material; and, as a third component, at least one type of organic solvent. In formula (A), ring A, ring B, and ring C each independently represent an aryl ring or a hetero aryl ring, Y
1
is B, and X
1
and X
2
each independently represent O or N—R wherein at least one of X
1
and X
2
is N—R.

This disclosure provides compounds and methods of using those compounds to treat metabolic disorders and hyperproliferative disorders, including administration of the compounds in conjunction with hormone receptor antagonists. Compounds of the invention may also find use in treating cancer. Presented herein are novel compounds bearing a perhaloalkylsulfonamide moiety. Such compounds, in addition to being highly effective SREBP inhibitors, are also unexpectedly highly bioavailable in vivo. Heteroaromatic compounds bearing sulfonamide groups are prone to several ionic states, based on the inherent pKa values.
