Palladium-catalyzed carbonylative synthesis of alkynones from aryl iodides and phenylpropiolic acid employing formic acid as the CO source
Li, Chong-Liang,Zhang, Wan-Quan,Qi, Xinxin,Peng, Jin-Bao,Wu, Xiao-Feng
, p. 9 - 11 (2017)
A palladium-catalyzed procedure for the decarboxylative-carbonylation of phenylpropiolic acid with iodobenzenes to the corresponding alkynones with formic acid as carbon monoxide source has been developed. Various alkynones were produced in moderate to good yields.

Three novel polystyrene supported selenol esters were synthesized and used as acyl transfer agents to prepare α, β-acetylenic ketones by reaction with alkynylcoppers.
Catalytic activity of palladium acyclic diaminocarbene complexes in the synthesis of 1,3-diarylpropynones via Sonogashira reaction: Cross- versus homo-coupling
Ryabukhin, Dmitry S.,Sorokoumov, Viktor N.,Savicheva, Elizaveta A.,Boyarskiy, Vadim P.,Balova, Irina A.,Vasilyev, Aleksander V.
, p. 2369 - 2372 (2013)
Sonogashira cross-coupling of aryl acetylenes and aroyl chlorides catalyzed by palladium(II) acyclic diaminocarbene complexes was investigated. Reactions were carried out with 0.04 mol % of the catalysts, all of which demonstrated high stability and activ
Organoborane-catalyzed selective 1,2-reduction of alkynones with hydride transfer: Synthesis of benzyl alkynes
Zhai, Lele,Yang, Zhigang,Man, Qinghong,Yang, Mingyu,Ren, Yangqing,Wang, Lei,Li, Huilin,She, Xuegong
, (2022/01/28)
Benzyl alkynes are important organic building blocks in organic synthesis. We report herein a B(C6F5)3-catalyzed site-selective 1,2-reduction of readily available alkynones to access benzyl alkyne derivatives. Under the de
Straightforward Stereoselective Synthesis of Seven-Membered Oxa-Bridged Rings through in Situ Generated Cycloheptenol Derivatives
Wang, Mengdan,Yin, Liqiang,Cheng, Lu,Yang, Yajie,Li, Yanzhong
, p. 12956 - 12963 (2021/09/13)
An iodine-mediated stereoselective synthesis of seven-membered oxa-bridged rings via in situ generated cycloheptenols was reported. This process was realized through the combination of C-C σ-bond cleavage and C-O bond-forming reactions in a one-pot fashion from simple and easily accessible raw materials. The formation of carbon radicals initiated by I2 was the key to the reaction.
Sc(OTf)3-catalyzed [3 + 2]-cycloaddition of nitrones with ynones

An efficient approach to access functionalized (2,3-dihydroisoxazol-4-yl) ketones has been developed by reacting nitrones 4 with ynones 7 or terminal ynones 10 in a one-pot fashion. The reaction went through a formal Sc(OTf)3-catalyzed [3 + 2]-cycloaddition process to generate a number of functionalized (2,3-dihydroisoxazol-4-yl) ketones 11aa-11aw, 11ba-11la and 12aa-12ae in moderate to good yields.
