Zhang, Na,Wang, Taisheng,Bu, Xiaohai,Wu, Qiong,Zhang, Zewu
, p. 1748 - 1755 (2019/08/02)
Two bola-amphiphilic small molecules, based on the diphenylanthracene skeleton structure, namely, BASM-1 and its functionalized small molecule BASM-2, were designed and synthesized. The self-assembly behavior and mechanism of these two molecules in aqueou
H3PW12O40-catalysed alkylation of arenes and diveratrylmethanes: Convenient routes to triarylmethanes and to symmetrical and unsymmetrical 9,10-diaryl-2,3,6,7-tetramethoxyanthracenes

An efficient method for the synthesis of triarylmethanes and difurylarylmethanes through solventless reactions between aldehydes and arenes in the presence of H3PW12O40 as a reusable catalyst under thermal and microwave irradiation conditions has been developed. H3PW12O40-catalysed one-pot consecutive Friedel-Crafts reactions between veratrole and aldehydes were also applied as a convenient protocol for the preparation of symmetrical 9,10-diaryl-2,3,6,7- tetramethoxyanthracenes.
Convenient synthesis of triarylmethanes and 9,10-diarylanthracenes by alkylation of arenes with aromatic aldehydes using acetyl bromide and ZnBr2/SiO2

, p. 2537 - 2540 (2008/09/21)
Reaction of electron-rich arenes with acetyl bromide and aldehydes in the presence of silica gel-supported zinc bromide was carried out in benzene to give selectively the corresponding triarylmethanes or 9,10-diarylanthracenes in high yields depending upon the ratio of an arene and an aldehyde. The mild conditions employed are especially noteworthy.
Method for producing biaryl compound
-
, (2008/06/13)
There is disclosed a method for producing a biaryl compound of formula (I): wherein R1 is the same or different and independently denotes a substituted or unsubstituted hydrocarbon group or the like, A and B denote an aromatic hydrocarbon ring having from 6 to 14 carbon atoms or the like, k and m independently denote an integer of from 0 to 5, and 1 denotes an integer of 1 or 2, which method is characterized by reacting an aromatic compound of formula (II): wherein R1, k and l denote the same as defined above, and X1 denotes a leaving group, with a Grignard reagent of formula (III): (R2). 9MgX2 (IIIg) wherein R2, B, and m denote the same as defined above and X2 denotes chlorine or the like, in the presence of a cyclic ether, or an acyclic ether having two or more ether oxygens in the molecule and a nickel catalyst.
Br?nsted- and Lewis acid-catalyzed cyclization giving rise to substituted anthracenes and acridines
Goossens, Raf,Smet, Mario,Dehaen, Wim
, p. 6605 - 6608 (2007/10/03)
A versatile acid-catalyzed method for the preparation of symmetrically and unsymmetrically substituted 9,10-diphenylanthracenes is explored. Diveratrylmethanes are prepared and converted into 10-phenylanthracene-9-carbaldehydes by Lewis acid catalysis and into 9-phenylacridines by reduction.
ECHANGE DE SUBSTITUANTS EN SERIE ANTHRACENIQUE PAR CYCLO-ADDITIONS SUIVIES D'ELIMINATIONS SPONTANEES; APPLICATION A LA SYNTHESE D'UN CAPTEUR HYDROSOLUBLE D'OXYGENE SINGULET
Aubry, J. M.,Schmitz, C.,Rigaudy, J.,Cuong, Nguyen Kim
, p. 623 - 628 (2007/10/02)
Condensation of benzaldehyde with veratrole in acidic media affords a one-pot synthesis of 2,3,6,7-tetramethoxy-9,10-diphenylanthracene 1f.The reaction of 1f with dimethyl acetylenedicarboxylate does not yield the expected adduct but leads directly to the tetramethyl 9,10-diphenylanthracene-2,3,6,7-tetracarboxylate 9b and other products, through successive cyclo-additions followed by spontaneous eliminations of dimethoxyacetylene or methoxycarbyne.
