Abstract The decarboxylative coupling of diversely substituted benzoic acids with internal alkynes proceeds smoothly in the presence a [RhCl(cod)]2/1,2,3,4-tetraphenyl-1,3-cyclopentadiene catalyst system to selectively produce highly naphthalene derivatives. is applicable constructing anthracene and benzo­[c]thiophene frameworks through reactions naphthoic thiophene-2-carboxylic acids, respecti...

A straightforward synthesis of phenols from aryl boronic acids has been demonstrated using benzoic acid as a catalyst. Variety arylboronic bearing electron rich and withdrawing substituents gave the respective in good yields.

A new approach to protodecarboxylation is described that enhances the substrate scope for benzoic acids. The reaction uses oxidative radical conditions to decarboxylate a variety of acids in acetonitrile.

The non-anthocyanin phenolic compounds in wines from five grape cultivars (Zuo Shan Yi, Zuo Shan Er, Shuang Hong, Shuang You and Shuang Feng) of Vitis amurensis and two hybrid cultivars (Zuo Hong Yi and Zuo You Hong) were examined by high-performance liquid chromatography/electrospray ionization tandem mass spectrometry (HPLC/ESI-MS/MS) technique in this study. The non-anthocyanin phenolic comp...

Thirty-four thermophilic Bacillus sp. strains were isolated from decayed wood bark and a hot spring water sample based on their ability to degrade vanillic acid under thermophilic conditions. It was found that these bacteria were able to degrade a wide range of aromatic acids such as cinnamic, 4-coumaric, 3-phenylpropionic, 3-(p-hydroxyphenyl)propionic, ferulic, benzoic, and 4-hydroxybenzoic ac...

A number of prenylated benzoic acids derivatives with interesting biological activities have been previously isolated and characterized from different species of piperaceae family. Several Piper species contained structurally similar compounds with diverse biological activities such as anti-bacterial, anti-fungal, insecticidal as well as anti-parasitic all of which produces compounds that can b...
