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.]. This method was also used for the synthesis of ((trifluoromethyl)thio)arenes ArSCF3 via trifluoromethylthiolation of arenes using electrophilic N-(trifluoromethylthio)saccharin as SCF3 reagent. This catalyst-free protocol offered good yields for a wide range of arenes and showed good functional group tolerance without any protecting groups.

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.
