Transition metal-free domino aryl-aryl coupling/phospha-Michael addition of diarylphosphinite to α,β-unsaturated ketones triggered by alkaline hydrolysis of (4-(2-alkenoyl)phenyl)triarylphosphonium salts
Huang, Wenhua,Xue, Jing-Yu
, (2021/11/08)
Alkaline hydrolysis of a variety of (4-(2-alkenoyl)phenyl)triarylphosphonium bromides is reported. This hydrolysis triggers coupling of 4-(2-alkenoyl)phenyl with one aryl via phosphorus(V). Both diarylphosphinite and an α,β-unsaturated ketone are in situ generated and then undergo phospha-Michael addition to provide β-diarylphosphoryl ketones bearing a biaryl moiety in 27–70% yields in the absence of a transition metal.

Studies of NMR Chemical Shifts of Chalcone Derivatives of Five-membered Monoheterocycles and Determination of Aromaticity Indices
Jeong, Eun Jeong,Lee, In-Sook Han
, p. 668 - 673 (2019/07/12)
A series of the chalcone derivatives of the five-membered monoheterocyclic compounds, (E)-1-aryl-3-heteroarylpropen-1-ones, were prepared by aldol condensation of the corresponding aldehydes of thiophene, pyrrole, and furan with m- and p-substituted acetophenones. Similar condensation of the acetyl compounds of the heterocycles with m- and p-substituted benzaldehydes gave another series of the chalcone derivatives, (E)-1-heteroaryl-3-arylpropen-1-ones. The 13C chemical shift values (δC) of the chalcone derivatives were determined in order to find if they correlated with the Hammett σ values. A good correlation, especially for the β-C for both series, was found for the 13C chemical shift values (δC) of the chalcone derivatives with the Hammett σ values. The chemical shift values of the β-C of the heterocyclic compounds were plotted against those of the benzene derivatives. The resulting slopes were found to be close to the values of the aromaticity indices.
