Luo, Fen-Tair,Jeevanandam, Arumugasamy,Bajji, Ashok Channaveerappa
, p. 121 - 122 (1999)
The use of palladacycle catalyst to the transformation of various (Z)- β-iodo-β,γ-enones into the corresponding 2,5-disubstituted furans in good yields at room temperature was described. The comparison of using other kind of palladium catalysts under the
A novel palladium-catalyzed tandem dimerization and cyclization of acetylenic ketones. A convenient method for 3,3'-bifurans

Alkynones undergo rearrangement in the presence of Pd(PPh3)4 and triethylamine in tetrahydrofuran at room temperature to give 2,5-substituted furans, but under similar conditions PdCl2(PPh3)2, by a tandem dimerization and cyclization, gives 3,3'-bifurans predominantly.
Bifunctional phosphine ligand-enabled gold-catalyzed direct cycloisomerization of alkynyl ketones to 2,5-disubstituted furans
Hu, Xiaojun,Zhou, Bingwei,Jin, Hongwei,Liu, Yunkui,Zhang, Liming
, p. 7297 - 7300 (2020/07/14)
An efficient synthesis of 2,5-disubstituted furans directly from alkynyl ketones has been developed via tandem gold(i)-catalyzed isomerization of alkynyl ketones to allenyl ketones and cycloisomerization. The key to the success of this chemistry is the use of a biphenyl-2-ylphosphine ligand featuring a critical remote tertiary amino group.
Direct arylation of heteroarenes catalyzed by a palladium-1,10- phenanthroline complex
Takita, Ryo,Fujita, Daichi,Ozawa, Fumiyuki
supporting information; experimental part, p. 959 - 963 (2011/06/17)
A new entry in direct arylation of heteroarenes using Pd(OAc)2 and 1,10-phenanthroline as a nitrogen-based ligand is reported. The long induction period observed at the initial stage of the reaction was effectively reduced by modification of th
