Liu, Haocheng published the artcileA comparative study of aromatic characterization of Yingde Black Tea infusions in different steeping temperatures, SDS of cas: 21834-92-4, the main research area is Yingde black tea steeping temperature aromatic characterization.

Black tea, known for its unique aroma, is one of the most popular non-alc. beverages. Because of complex aroma composition, studying black tea aroma has attracted widespread attention. The aim of this study was to evaluate the effect of different steeping temperatures (60°C, 70°C, 80°C, and 95°C) on the aroma composition of Yingde black tea for the first time. A total of 157 volatile compounds were identified by gas chromatog.-mass spectrometry (GC-MS). These compounds can be divided into 11 categories, including alcs., esters, ketones, aldehydes, terpenes and sulfides. The types of different volatile compounds and contents in tea infusion samples show a pos. correlation with steeping temperature A total of 16 main aromatic compounds were identified though the comparison anal. of gas chromatog.-olfactometry (GC-O FD â‰?32) data and odor activity value (OAV value â‰?1), including β-damascone, β-ionone, linalool, Et hexanoate, di-Me sulfide, di-Me trisulfide, nonanal, Me salicylate, 3-hexenyl isovalerate, cedrol, and longifolene. A correlation of characteristic aroma data with descriptive sensory anal. (DSA) data clearly established that different steeping temperatures result in different overall aroma qualities of the black tea, indicating that steeping temperature is a key parameter affecting the aroma composition

Wu, Yaxing published the artcileElectrochemical and direct C-H methylthiolation of electron-rich aromatics, Safety of 1,3-Dimethoxybenzene, the main research area is thiomethylated aromatic compound preparation; electron rich aromatic compound electrochem methylthiolation.

The electrochem.-induced C-H methylthiolation of electron-rich aromatics for the synthesis of thiomethylated aromatics ArSR [R = Me, Et, n-Pr; Ar = 4-MeOC6H4, 4-MeNHC6H4, 2-MeO-1-naphthyl, etc.] was accomplished via a three component cross-coupling strategy. Potassium thiocyanate (KSCN) as both the supporting electrolyte and sulfur source and methanol as the methylation reagent were used. This protocol was versatile for various (hetero)aromatic compounds such as aniline, anisole and indole. The reaction proceeded under mild conditions without any metal catalyst, exogenous oxidant and highly toxic sulfur reagent. Importantly, such an electrochem.-induced methylthiolated reaction could be easily scaled up with good efficiency.

Zhang, Hao-Ran published the artcileDirect Arene Trifluoromethylation Enabled by a High-Valent CuIII-CF3 Compound, Related Products of isoquinoline, the main research area is arene heteroarene trifluoromethylation copper; Arenes; C−H Functionalization; High-Valent Copper Species; Radical Reaction; Trifluoromethylation.

Direct C-H trifluoromethylation of arenes and heteroarenes poses an important synthetic challenge that is highly desirable. High-valent CuIII-CF3 compounds have often been invoked in copper-mediated trifluoromethylation reactions, but the fundamental reactivity toward arenes is elusive. Herein, direct C-H trifluoromethylation of arenes/heteroarenes by a high-valent CuIII-CF3 compound is disclosed for the first time. The CuIII-CF3 compound serves CF3 radical and a CuII oxidant by homolytic cleavage of a CuIII-CF3 bond, which engage synergistically in a SEAr type reaction with arenes. The presence of K2S2O8 co-oxidant can significantly improve the reaction yields. This reaction shows good efficiency, broad functional group tolerance, and the potential in late-stage functionalization. The reactivity of high-valent CuIII-CF3 compounds disclosed in this study represents an important progress in organofluorine and CuIII chem.

An efficient and straightforward hydrogen-bonding-network-assisted regioselective sulfenylation of electron-rich arenes with N-thiosuccinimides was developed for the synthesis of thioarenes ArSR [R = c-hexyl, 4-MeC6H4, 2-FC6H4, etc.; Ar = 4-NMe2C6H4, 1-methylindol-3-yl, 5-MeO-1H-indol-3-yl, etc.].

Clare, Daniel published the artcileChemospecific Cyclizations of α-Carbonyl Sulfoxonium Ylides on Aryls and Heteroaryls, HPLC of Formula: 104-01-8, the main research area is chemospecific cyclization carbonyl sulfoxonium ylide aryl heteroaryl; safety advantage carbonyl sulfoxonium ylide; chemospecifity; cyclization; hexafluoroisopropanol; iridium; sulfoxonium.

The functionalization of aryl and heteroaryls using α-carbonyl sulfoxonium ylides without the help of a directing group has remained so far a neglected area, despite the advantageous safety profile of sulfoxonium ylides (safety: an α-diazo ketone was potentially explosive, whereas an α-carbonyl sulfoxonium ylide was not). Described herein are the cyclizations of α-carbonyl sulfoxonium ylides onto benzenes, benzofurans and N-p-toluenesulfonyl indoles in the presence of a base in HFIP [e.g., I â†?II (91%) in presence of K2CO3 in HFIP], whereas pyrroles and N-Me indoles undergo cyclization in the presence of an iridium catalyst. Significantly, these two sets of conditions are chemospecific for each groups of substrates.
