Wu, Bin;Wang, Jianing;Liu, Xingchen;Zhu, Rong research published 《 Bicyclo[2.2.0]hexene derivatives as a proaromatic platform for group transfer and chemical sensing》, the research content is summarized as follows. Here the design, preparation, synthetic utility, and sensing application of a class of proarom. structures, namely bicyclo[2.2.0]hexene (BCHs) derivatives I [R = allyl, i-Pr, Bn, etc.] was reported. Building on a valence isomerism concept, they featured modular and easy synthesis as well as high thermal stability, and could be oxidatively activated under mild conditions. New alkyl transfer reactions using BCHs as a radical donor were developed to showcase the utility of their proaromaticity. Moreover, the redox-triggered valence isomerization of a quinoline-derived BCH led to colorimetric and fluorescent responses toward vapors of electrophilic reagents in solution and solid phase, resp. This optical response was showed to involved a 1,3-cyclohexadiene structure that possesses an intramol. charge transfer excited state with interesting aggregation induced emission (AIE) character. Thus, the potential of BCHs was demonstrated as a versatile platform for the development of new reagents and functional materials.
