Markiewicz, Grzegorz;Orwat, Bartosz;Piechocki, Milosz;Jankowska, Kamila;Kownacki, Ireneusz;Stefankiewicz, Artur R. research published 《 A substituent-induced post-assembly modification cascade of a metallosupramolecular imine-type Co-complex》, the research content is summarized as follows. Here, the authors report a reaction cascade employing the substituent-induced post-assembly modification of a Co(III) complex. Unexpectedly, the (triisopropylsilyl)alkynyl moiety introduced to the Sonogashira reaction with the bromo-functionalized Co(III) assembly plays a “Trojan horse” role, triggering a subsequent, second step of the cascade, i.e. Co(III) to Co(II) reduction The reported substituent-activated Sonogashira-redox cascade reaction might set a new direction in the construction of specific chem. sensors.
