Theoretical investigation on the palladium-catalyzed selective formation of spirocyclenes from dienallenes
Publication date: Available online 9 February 2020Source: Journal of Organometallic ChemistryAuthor(s): Jing Zhang, Qingli Zhang, Zhenyuan Zhu, Bingkai WangAbstractThe mechanisms of Pd(TFA)2-catalyzed cascade reactions of dienallenes and alkyne have been investigated by density functional theory (DFT) calculations. The computational results indicate that spiro[4.4]nonene rather than spiro[3.4]octene is the product in DCE solvent, due to the lower free-energy barrier for CO insertion from vinylpalladium intermediate than the competing olefin insertion, which is consistent with the experimental fact. The origin of regioselec...

Palladium/aluminium-cocatalyzed carbonylative synthesis of 2-chloroethyl benzoates from epoxides and aryl iodides
Publication date: Available online 16 January 2020Source: Journal of Organometallic ChemistryAuthor(s): Xinxin Qi, Zhi-Peng Bao, Chen-Yang Hou, Wei-Feng Wang, Xiao-Feng WuAbstractA new straightforward and efficient procedure for the palladium/aluminium-cocatalyzed carbonylative synthesis of 2-chloroethyl benzoates from epoxides and aryl iodides has been developed. By using TFBen (benzene-1,3,5-triyl triformate) as the CO source and LiCl as the chloride source, AlCl3-catalyzed regioselective ring-opening of epoxides was merged successfully with the palladium-catalyzed carbonylative cross-coupling of aryl iodides. A variety ...

Metal complexes of ferrocenyl-substituted Schiff base: Preparation, characterization, molecular structure, molecular docking studies, and biological investigation
Publication date: Available online 11 January 2020Source: Journal of Organometallic ChemistryAuthor(s): Walaa H. Mahmoud, Reem G. Deghadi, Gehad G. MohamedAbstractThe organometallic Schiff base ligand (L) was synthesized by reacting 2-acetylferrocene with 1,8-naphthalenediamine in 1:1 M ratio. The reaction of Schiff base with some transition metal ions mains to mono-species of chelates. The ligand and its metal complexes were characterized using elemental analysis (C, H, N and M), molar conductivity, FT-IR, UV–Vis, 1H NMR, SEM and mass spectrometry. Also, their TG and DTG studies were investigated. All complexes ha...
