Tuxworth, Luke,Baiget, Lise,Fox, Mark A.,Dyer, Philip W.,Phanopoulos, Andreas,Metters, Owen J.,Batsanov, Andrei S.,Howard, Judith A. K.
, p. 10413 - 10415,3 (2012)
N-Diphenylphosphino-7-aza-benzobicyclo[2.2.1]hept-2-ene (2) behaves as a chelating phosphine-alkene ligand for Pd0 and PdII, promoting direct alkyl-alkyl and indirect alkyl-halide reductive elimination reactions due to the stabilisation of the resulting bis(phosphine-alkene)Pd 0 complex.

, p. 4438 - 4448 (2015)
An efficient and scalable synthesis of various enantiopure 1,3- disubstituted isoindolines is reported. The base catalyzed nucleophilic fragmentation of a rigid overbred template is established with various substrates to afford the corresponding 1,3-disub
Indium-Mediated Intramolecular Reaction of N-(2-Iodobenzoyl)azabenzonorbornadienes: A General Access to Dihydrobenzo[c]phenanthridinones
Liu, Yang,Lei, Kang,Liu, Na,Sun, Dong-Wei,Hua, Xue-Wen,Li, Ya-Juan,Xu, Xiao-Hua
, p. 5495 - 5503 (2016)
An efficient synthesis of dihydrobenzo[c]phenanthridinones was achieved by utilizing an indium(0)-mediated intramolecular cyclization reaction under ligand- and base-free conditions. A variety of functional groups were tolerated in the present protocol.

One-Pot Generation of Functionalized Benzynes from Readily Available 2-Hydroxyphenylboronic Acids
Ikawa, Takashi,Sun, Jingkai,Takagi, Akira,Akai, Shuji
, p. 3383 - 3392 (2020/03/10)
We developed a one-pot method for the generation of benzynes from a range of readily available 2-hydroxyphenylboronic acids. This method features the in situ activation of both boronic acid and hydroxyl groups of the substrate to enhance benzyne generation at 60 °C. Such mild conditions facilitate the generation of functionalized benzynes that immediately react with diverse arynophiles to produce multisubstituted fused benzenes.
Arynes and Their Precursors from Arylboronic Acids via Catalytic C-H Silylation
Devaraj, Karthik,Ingner, Fredric J.L.,Sollert, Carina,Gates, Paul J.,Orthaber, Andreas,Pilarski, Lukasz T.
, p. 5863 - 5871 (2019/04/16)
A new, operationally simple approach is presented to access arynes and their fluoride-activated precursors based on Ru-catalyzed C-H silylation of arylboronates. Chromatographic purification may be deferred until after aryne capture, rendering the arylboronates de facto precursors. Access to various new arynes and their derivatives is demonstrated, including, for the first time, those based on a 2,3-carbazolyne and 2,3-fluorenyne core, which pave the way for novel derivatizations of motifs relevant to materials chemistry.
