Dialkyl Ethers and Sacrificial Zinc: Oxide Synthons for Calcium tert‐Butoxide Formation
Angewandte Chemie, EarlyView.When treated with dialkyl ethers, [(BDI)Ca‐μ‐H‐Zn(t‐Bu)2(η6‐C7H8)] (BDI = HC{C(Me)NDipp}2 initiates a sequence of twofold ether dealkylation and oxide sequestration as tert‐butoxide in a process predicated on a combination of extreme basicity and a cooperative redox process administered by the dissimilar constituent metals. (Generative AI (ChatGPT) was

Angewandte Chemie, EarlyView.A meso‐carboxamide‐substituted BODIPY fluorescent probe reports myeloperoxidase (MPO) activity via electrophilic chlorination by MPO‐derived HOCl, generating a highly emissive chlorinated product with a ca. 40 nm bathochromic shift. Applications in quantitative MPO assays, cellular imaging of MPO‐derived HOCl, redox‐dependent discrimination of cancer ...
