Rhodium-catalyzed cross-coupling of alkenyl halides with arylboron compounds
Matsuda, Takanori,Suzuki, Kentaro,Miura, Norio
, p. 3396 - 3400 (2013)
The rhodium(I)-catalyzed reaction between arylboronic esters and excess 1,2-dichloroethene selectively afforded (2-chlorovinyl)arenes. Double arylation yielding 1,2-diarylethenes was observed when 1,2-dibromoethene was reacted with 2.5 equivalents of aryl
Homocoupling of arylboronic acids catalyzed by simple gold salts
Matsuda, Takanori,Asai, Taro,Shiose, Shigeru,Kato, Kotaro
experimental part, p. 4779 - 4781 (2011/10/05)
A range of arylboronic acids undergo a homocoupling reaction in the presence of catalytic amount of gold salts to yield symmetrical biaryls. Alkenylboronic acids, arylboronic esters, and arylborates also participate in the gold-catalyzed homocoupling reaction.
Preparation of functionalized aryl- and heteroarylpyridazines by nickel-catalyzed electrochemical cross-coupling reactions

(Chemical Equation Presented) A general efficient electrochemical method for the preparation of aryl- and heteroarylpyridazines in a nickel-catalyzed cross-coupling reaction of 3-chloro-6-methoxypyridazine and 3-chloro-6- methylpyridazine with a range of functionalized aryl or heteroaryl halides is reported.
Oxygen-promoted Pd(II) catalysis for the coupling of organoboron compounds and olefins
Jung, Young Chun,Mishra, Rajesh Kumar,Yoon, Cheol Hwan,Jung, Kyung Woon
, p. 2231 - 2234 (2007/10/03)
(Matrix presented) Reported herein is a mild and efficient Pd(ll) catalysis, leading to the formation of carbon-carbon bonds between a broad spectrum of organoboron compounds and alkenes. Molecular oxygen was employed to reoxidize the resultant Pd(0) species back to Pd(ll) during catalytic cycles. This oxygen protocol promoted the desired Pd(ll) catalysis, whereas it retarded competing Pd(0) catalytic pathways such as Heck or Suzuki couplings.
Palladium-catalyzed cross-coupling of bromobenzenes, containing an acetyl or a formyl group, with organozinc reagents
Okamoto, Yuzo,Yoshioka, Katsuaki,Yamana, Tsuyoshi,Mori, Hiroshi
, p. 285 - 290 (2007/10/02)
The reaction of organozinc halides RZnX (R=Bu, Ph; X=Cl, Br) with m- and p-bromoacetophenones in the presence of PdCl2(PPh3)2 in THF/HMPA (THF=tetrahydrofuran; HMPA=N,N,N',N',N'',N''-hexamethylphosphoric triamide) takes place chemoselectively to give the corresponding m- and p-R-substituted acetophenones in high yields.Similarly reaction of RZnX with p-bromobenzaldehyde also proceeds chemoselectively to give the p-R-substituted benzaldehyde in good yields.
