Finding a relationship between kinetics and thermodn. may be difficult. However, semi-empirical rules exist to compensate for this shortcoming, among which the Bell-Evans-Polanyi (B-E-P) principle is an example for reactions involving bond breakage and reformation. We expand the B-E-P principle to a new territory by probing photoinduced structure planarization (PISP) of a series of dibenz[b,f]azepine derivatives incorporating bent-to-planar and rotation motion. The latter involves twisting of the partial double bond character, thereby inducing a barrier that is substituent dependent at the para N-Ph position. The transition-state structure and frequency data satisfy and broaden the B-E-P principle to PISP reactions without bond rearrangement. Together with dual emissions during PISP, this makes possible harnessing of the kinetics/thermodn. relationship and hence ratiometric luminescence properties for excited-state structural transformations. In addition to this study using 1-Bromo-4-iodobenzene, there are many other studies that have used 1-Bromo-4-iodobenzene(cas: 589-87-7Quality Control of 1-Bromo-4-iodobenzene) was used in this study.
1-Bromo-4-iodobenzene(cas: 589-87-7) has been employed as reagent for in situ desilylation and coupling of silylated alkynes, as starting reagent in the total syntheses of ent-conduramine A and ent-7-deoxypancratistatin (alkaloids), as substrate in copper-free Sonogashira coupling in aqueous acetone in synthesis of β,β,dibromostyrenesQuality Control of 1-Bromo-4-iodobenzene
