Benzoladderene Mechanophores: Synthesis, Polymerization, and Mechanochemical Transformation
Yang, Jinghui,Horst, Matias,Romaniuk, Joseph A. H.,Jin, Zexin,Cegelski, Lynette,Xia, Yan
, p. 6479 - 6483 (2019)
We have previously reported a polymechanophore system, polyladderene, which underwent dramatic bond rearrangement in response to mechanical force to yield semiconducting polyacetylene. Herein, we report the scalable synthesis of benzoladderenes as new mec
2,3-Dihalo- and 2,3,6,7-Tetrahaloanthracenes by Vollhardt Trimerization
Hoffmann, Hendrik,Mukanov, Diana,Ganschow, Michael,Rominger, Frank,Freudenberg, Jan,Bunz, Uwe H. F.

We efficiently synthesized otherwise difficult to obtain 2,3- and 2,3,6,7-halogenated anthracenes with diverse east/west substituents. Key steps involve the (i) Vollhardt cyclization of bis(propargyl)benzenes with bis(trimethylsilyl)acetylene, (ii) halo-desilylation introducing chlorine, bromine, or iodine substituents, and (iii) dehydrogenation. Pd catalysis allows selective functionalization at the anthracenes' east/west positions. A tetrahydropentacene is synthesized and derivatized via the same strategy, employing tetrapropargylbenzene.
A new and simple synthetic approach to functionalized sulphone derivatives by the Suzuki-Miyaura cross-coupling reaction

, p. 227 - 231 (2007/10/03)
Synthesis of various highly functionalized sulphone derivatives are reported via the bis Suzuki-Miyaura (SM) cross-coupling reaction as a key step. In this regard, the dibromo sulphone 8, prepared from the corresponding sultine derivative 7 by thermal rea
