Although the direct conversion of gaseous acetylene into value‐added liquid commodity chemicals is becoming increasingly attractive, the majority of the established methodologies are focused on cross‐coupling, hydro‐functionalization, and polymerization. Herein, we describe a 1,2‐difunctionalization method that inserts acetylene directly into readily available bifunctional reagents. This method provides access to diverse C2‐linked 1,2‐bis‐heteroatom products in high regio‐ and stereoselectivity along with opening up previously unexplored synthetic directions. In addition, we demonstrate this method's synthetic potential by converting the obtained products into diverse functionalized molecules and chiral sulfoxide‐containing bidentate ligands. Using a combination of experimental and theoretical methods, the mechanism for this insertion reaction was investigated. [ABSTRACT FROM AUTHOR]

"Fengren" is a reference of identity from The Book of Poetry. Classical Chinese poetics has formed a unique evaluation of the identity relevant to the discourse of "Fengren," which is suggestive of the ethics in The Book of Poetry. In contrast to the identity of "Saoren," "Fengren"'s identity is linked with political criticism and sarcasm. As "Feng" and "Ya" are gradually distinguished, "Fengren" is differentiated from "Cairen" and becomes increasingly recognizable in terms of expressing meanings metaphorically through things. Thanks to the author community and the content of "Feng," the style of folk lyric is formed with "Fengren" at its centre, which, as a result, foregrounds a different evaluation of popular poetics represented by "the style of Fengren." It is thus essential to understand the poetic value of "Fengren" and its contribution to the identity of classical Chinese poets. [ABSTRACT FROM AUTHOR]

A Wittig-type reaction was achieved by radical cation salt induced aerobic oxidation of Csp3−H bonds. Different from the 'standard' version of the Wittig reaction, in which a carbon-carbon double bond is formed from a carbonyl, carbonyl groups can be installed by similar process.

Using an aromatization-blocked strategy, the 1,2-dihydroquinoline skeleton was efficiently constructed by sp3 CH bond oxidation of N-arylalaninates under catalytic radical cation salt-promoted conditions. Investigation of the reaction scope shows broad generality and good functional group tolerance. This method provides a new way to synthesize 1,2-dihydroquinoline derivatives from easily accessible starting materials. [ABSTRACT FROM AUTHOR]

Designed by fragment-reassembly strategy, the reaction between glycine esters and cyclic enol ethers was achieved in the catalysis of TBPA +· /O 2 , yielding a series of quinoline-fused lactones and 2,3-disubstituted quinolines. This approach provided an efficient method to construct quinoline skeleton, in which two new rings and two new C–C bonds were built in one pot. [ABSTRACT FROM AUTHOR]

A facile and efficient radical cation salt-induced approach to dihydroquinazoline derivatives has been developed by sp 3 C H oxidation, and the method uses readily available glycine esters as the starting material under aerobic oxidation conditions without addition of any additive. The present method provides a convenient and practical route for construction of quinazoline skeleton. [ABSTRACT FROM AUTHOR]

The oxidation of sp 3 C H bonds in N- alkylhydrazides was achieved en route to the efficient synthesis of a broad series of 1,3,4-oxadiazoles. Mechanistic studies have revealed that N- acylhydrazone is a key intermediate in this catalytic transformation. [ABSTRACT FROM AUTHOR]
