Catalyst-Directed Chemoselective Double Amination of Bromo-chloro(hetero)arenes: A Synthetic Route toward Advanced Amino-aniline Intermediates
Mikhailine, Alexandre A.,Grasa Mannino, Gabriela A.,Colacot, Thomas J.
, p. 2301 - 2305 (2018/04/30)
A chemoselective sequential one-pot coupling protocol was developed for preparing several amino-anilines in high yield as building blocks for active pharmaceutical ingredients (APIs). Site (Cl vs Br on electrophile) and nucleophile (amine vs imine) selectivity is dictated by the catalyst employed. A Pd-crotyl(t-BuXPhos) precatalyst selectively coupled the Ar-Br of the polyhaloarene with benzophenone imine, even in the presence of a secondary amine, while Pd-based RuPhos or (BINAP)Pd(allyl)Cl coupled the Ar-Cl site with secondary amines.
Polycyclic aromatic compound
-
Paragraph 1580; 1581; 1582, (2016/10/08)
The present invention addresses the problem of providing a novel polycyclic aromatic compound and an organic electroluminescent element using the same. The above problem is solved by providing a novel polycyclic aromatic compound in which a plurality of aromatic rings are connected by boron atoms, oxygen atoms, or the like, thereby increasing the number of options for organic EL element materials, and also solved by providing a superior organic EL element using said novel polycyclic aromatic compound as an organic EL element material.

, p. 9207 - 9210 (2007/10/03)
A series of 1,3-bis(diarylamino)benzenes as model precursors for 1D organic ferromagnetic metals were synthesized. Cyclic voltammetric measurements showed that the corresponding mono- and dication radicals with protecting groups were stable enough even at
