- Silica sulfuric acid as a highly efficient catalyst for the synthesis of diarylacetic acids
-
ABSTRACT: An efficient heterogeneous method for the synthesis of diarylacetic acids was developed utilizing silica sulfuric acid as a catalyst. The reaction is highly efficient with a small amount of catalyst for the combination of a variety of electron-n

- Rh-Catalyzed annulations of: N -methoxybenzamides with ketenimines: Synthesis of 3-aminoisoindolinones and 3-diarylmethyleneisoindolinones with strong aggregation induced emission properties
-
Rhodium-catalyzed C-H activation/annulation reactions of ketenimines with N-methoxybenzamides furnished 3-aminoisoindolin-1-ones and 3-(diarylmethylene)isoindolin-1-ones. The synthesized 3-(diarylmethylene)isoindolin-1-ones exhibited aggregation induced emissions in aqueous tetrahydrofuran solution and strong green-yellow emissions in solids.

- Palladium-catalyzed α-arylation of carboxylic acid derivatives with grignard reagent
-
The reaction of arylacetic acid with aryl halides in the presence of a palladium(0) catalyst proceeds with a Grignard reagent (2 equiv.) to afford diarylated acetic acids. Deprotonation was confirmed by treatment with allyl bromide, which revealed that th

- A Study of the Ferrous Ion-initiated SRN1 Reactions of Halogenoarenes with tert-Butyl Acetate and N-Acylmorpholine Enolates
-
A detailed preparative study is reported of the ferrous ion-initiated SRN1 reactions of a range of halogenoarenes with the sodium enolates of tert-butyl acetate, n-acetylmorpholine and a number of higher N-acylmorpholines.Smooth and rapid substitution occurs in many cases, and good to excellent yields were obtained of arylacetic esters or acids, arylacetamides and arylalkanamides.The broad scope and limitations of the process have been defined, and the possible role of the ferrous ion is discussed.

- THE CHEMISTRY OF SOME METHOXYCHLOR DERIVATIVES
-
The preparation of 1-chloro-2,2-bis(p-methoxyphenyl)ethylene (3a) and of 1-chloro-2,2-bis(p-hydroxyphenyl)ethylene (3b), required for a study of the microbial degradation of methoxychlor (1a) was reinvestigated.The methoxy compound (3a) was readily obtained by alkaline dehydrohalogenation of 1,1-dichloro-2,2-bis(p-methoxyphenyl)ethane (2a), but similar treatment of 1,1-dichloro-2,2-bis(p-hydroxyphenyl)ethane (2b) gave a chlorine-free compound, characterized as the diethyl acetal of 2,2-bis(p-hydroxyphenylacetaldehyde (5a) on the basis of spectroscopic evidence and comparison with a model compound.Also, 2,2-bis(p-methoxyphenyl)acetic acid (4a) and 2,2-bis(p-hydroxyphenyl)acetic acid (4b) were prepared and the solubility and p-values (ethyl acetate / water) of these acids were determined.
