report a facile transition-metal-freeapproach to sulfur-containing heteroacenes from fluorinated oligophenylenes. Unlike most existing methods, the presented approach is not restricted to simple dibenzothiophene derivatives and thus appears to be a useful tool for the synthesis of extended sulfur-containing heteroacenes. The incorporation of sulfur is unambiguously preprogrammed via the positions of

The stereoselective photocyclization was generally observed for other ketones (2–8) in acetonitrile solution (Table 1). The photo-products were easily dehydrated by treating with boron trifluoride etherate to give the corresponding benzothiophenes in high yields. Simple α-phenylthioketones are photoinert under the same conditions. The mechanism of this novel photocyclization of bisulfenylated ketones
A new process has been developed for the palladium(II)-catalyzedsynthesis of dibenzothiophene derivatives via the cleavage of C–H and C–S bonds. In contrast to the existing methods for the synthesis of this scaffold by C–H functionalization, this new catalytic C–H/C–S coupling method does not require the presence of an external stoichiometric oxidant or reactive functionalities such as C–X or S–H
开发了一种通过C-H 和 C-S 键裂解钯 ( II ) 催化合成二苯并噻吩衍生物的新工艺。与现有的通过 C-H 官能化合成该支架的方法相比,这种新的催化 C-H/C-S 偶联方法不需要存在外部化学计量氧化剂或反应性官能团,例如 C-X 或 S -H,允许其应用于复杂的 π 系统的合成。值得注意的是,该反应的产物形成步骤在于氧化加成步骤而不是还原消除步骤,使得该反应在机理上不常见。
