Anaerobic methanotrophic archaea from the genus ‘Ca. Methanoperedens’ are slow‐growing microorganisms utilizing a range of electron acceptors such as nitrate. A granular enrichment culture of ‘Ca. Methanoperedens vercellensis’ remains metabolically active during stepwise acidification of the medium down to pH 5.65, whereas its activity is inhibited by ...

1,2‐Aryl migration involving in situ‐generated alkyl iodine(III) species proceeds through a previously unrecognized 1,2‐C/I(III) dyotropic rearrangement. Migratory aryl fluorination, acetoxylation, and alkoxylation of 2‐alkyl‐2‐aryl‐3‐iodopropanoates provide α‐heterofunctionalized products, accompanied by aryl migration from the α‐ to the β‐position ...
