AgF-Mediated Homocoupling Reaction of Trialkoxy Aryl Silanes

AgF‐Mediated Electrophilic Amination of Alkoxyarylsilanes with Azodicarboxylates

“…[12] In the presence of other fluoride sources (CsF, CaF 2 , NaF and TBAF), the reaction completely stopped (entries [10][11][12][13]. Combination of silver salts and cesium fluoride that could be regarded equivalent to the in situ formation of AgF resulted in no formation of 3 a (entries [14][15][16]. Interestingly, about 40% of biphenyl was observed instead.…”

Copper‐Catalyzed Electrophilic Amination of Alkoxyarylsilanes

“…In the cases of other solvents, lower yields were observed (entries 2–4). Interestingly, a substantial amount of biphenyl was observed as an only observable by‐product, which would be due to the formation of arylsilver species followed by the known oxidative dimerization . Regarding the source of the copper catalyst, a slightly lower yield (54%) was observed with CuCl(IMes), and the yield dropped with dppe or with no ligand (entries 5–7).…”

Advance of Organosilane in Transition-Metal-Catalyzed C—H Functionalization for C—C Bond Formation

“…通过预先制备 的环钯六元环与芳基三烷氧基硅烷以化学计量反应也 可以得到相应的偶联产物, 这点为推测的机理提供了充 分的证据. 另外, Cu(OTf) 2 在这里不仅可以作为氧化剂 将 Pd(0)氧化成 Pd(II), 而且还可以有效地抑制苯基硅试 剂的自身偶联 [32] . Ofial 课题组 [36] 在 2011 年报道了芳香杂环与芳基三…”
