Abstract: The interaction of various 1,2-dibromides with NEt3 under various conditions (THF and DMF, respectively) at different temperatures was investigated. Our results from these reactions show that substrate dependent dehydrobrominations compete with reductive debrominations. A comprehensive… read more here.

DOI: 10.1021/acs.orglett.2c03538
Abstract: Herein, we disclose substrate-dependent rearrangements of 4-substituted N-sulfonyl-1,2,3-triazoles under Rh(II)-catalysis via denitrogenation. The reaction pathways included key 1,2-aryl migration via the formation of intermediatory phenonium ion, which is elusive so far with Rh-azavinyl carbenes. Intriguingly,… read more here.

DOI: 10.1039/d3qo00301a
Abstract: Transition metal catalyzed amination of allylic alcohols via π-allylmetal is generally accepted to undergo a nucleophilic attack mechanism. However, we herein found the possibility of the competition between the reductive... read more here.

DOI: 10.1111/1462-2920.15163
Abstract: Summary A LuxI/R‐like quorum sensing (QS) system (AfeI/R) has been reported in the acidophilic and chemoautotrophic Acidithiobacillus spp. However, the function of AfeI/R remains unclear because of the difficulties in the genetic manipulation of these… read more here.
