Kakesh,Sayyahi,Badri,Tahanpesar
, p. 1218 - 1220 (2019)
A new imidazolium-based poly(ionic liquid) has been synthesized and used as a robust heterogeneous catalyst for the preparation of phenacyl derivatives by an SN2 reaction of different phenacyl bromides with a broad range of nucleophiles. The products are obtained in high yields under mild conditions. The catalyst can be recycled efficiently.

, p. 12186 - 12190 (2015)
A novel protocol for the synthesis of α-iodoketones from alcohols has been developed. Using water as the reaction medium, ammonium iodide and Oxone was proven to be an efficient reagent system for this reaction and afforded the corresponding α-iodoketones in moderate to good yields. The generality of this reaction was demonstrated with various secondary alcohols such as benzylic alcohols and aliphatic alcohols (acyclic and cyclic).

, p. 11 - 16 (2016)
The present work trends to define an efficient phenacyl catalytic synthesis method employing a new nano-magnetite-supported organocatalyst. Polyethylene glycol (PEG) was bonded successfully onto silica coated ferrite and the resultant nanoparticles (PEG@SiO2@Fe3O4) characterized by fourier transform infrared spectroscopy (FT-IR), atomic force microscopy (AFM), thermal gravimetric analysis (TGA), vibrating sample magnetometry (VSM), energy dispersive X-ray analysis (EDAX) and X-ray diffraction (XRD) that exhibited a good catalytic activity in the reaction. The nanoparticles could be easily separated from the reaction mixture by an external magnet and reused in seven reaction cycles without significant loss of activity.

, p. 300 - 302 (2011)
In this letter, a mild and efficient procedure for synthesis of phenacyl derivatives under homogenous catalysis in the presence of tetrabutylammonium bromide in aqueous media is described. The nucleophilic substitution reactions were performed under ecofriendly conditions and gave the corresponding products in high yields and short reaction times.
Carbon-13 NMR Spectra of Some 4-Substituted Phenacyl Chlorides and Iodides
Olivato, Paulo Roberto,Guerrero, Sandra Alvarez,Rittner, Roberto
, p. 179 - 180 (1987)
The 13C NMR signals for some 4-substituted phenacyl chlorides and iodides were assigned.The carbonyl carbons exhibit upfield shifts compared with those of the corresponding 4-substituted acethophenones; in the chlorinated derivatives a downfield shift is observed for the α-methylene carbons, while a reverse effect occurs in the iodinated compounds.The chemical shifts of the aromatic ring carbons are in close agreement with those calculated using substituent chemical shifts.KEY WORDS 13C NMR 4-substituted pheacyl chlorides and iodides
A practical synthesis of α-bromo/iodo/chloroketones from olefins under visible-light irradiation conditions
Wang, Zhihui,Wang, Lei,Wang, Zhiming,Li, Pinhua,Zhang, Yicheng
supporting information, p. 429 - 432 (2020/02/29)
A practical synthesis of α-bromo/iodo/chloroketones from olefins under visible-light irradiation conditions has been developed. In the presence of PhI(OAc)2 as promoter and under ambient conditions, the reactions of styrenes and triiodomethane undergo the transformation smoothly to deliver the corresponding α-iodoketones without additional photocatalyst in good yields under sunlight irradiation. Meanwhile, the reactions of styrenes with tribromomethane and trichloromethane generate the desired α-bromoketones and α-chloroketones in high yields by using Ru(bpy)3Cl2 as a photocatalyst under blue LED (450–455 nm) irradiation.

, p. 621 - 629 (2015/10/12)
A simple preparative method has been developed for the synthesis of aryl(furfuryl) ketones, amides, and furylacetic acid esters, based on radical alkylation of furan derivatives at the α-position with O-ethyl(phenacyl)xanthogenates and phenacyl iodides in the presence of Fenton's reagent (H2O2/FeSO4·7H2O) in DMSO. The range of applicability and mechanisms for the formation of major and side products have been considered.
