Crystal Engineering with Symmetrical Threefold Acceptor-Substituted Triaminobenzenes
摘要:
The syntheses of threefold acceptor-substituted 1,3.5-triaminobenzene derivatives 2 - 6 and their crystal structure analyses are described. As accepters, nitro, trifluoromethylsulfone, and alkylsulfone groups are employed. The combination of hydrogen bonding, arene...arene and F ... F contacts leads to remarkably similar solid-state layer structures for sterically quite dissimilar molecules.

diaryl disulfides occurs through the S—S bond cleavage to form dihalo-, halonitro-, and halodinitrophenyl perfluoroalkyl sulfides. The latter type of compounds was obtained for the first time. The main side process is the perfluoroalkylation of the aromatic ring.
在二芳基二硫化物存在下,氙 (ii) 双(全氟烷烃羧酸盐)的热解通过 SS 键断裂发生,形成二卤代-、卤代硝基-和卤代二硝基苯基全氟烷基硫化物。后一类化合物是首次获得。主要的副过程是芳环的全氟烷基化。
