Stereochemical Control in the Matteson Reaction

Chemistry – A European Journal, Volume 32, Issue 40, 27 October 2026.
The Matteson homologation is a highly versatile method for the stereoselective insertion of carbenoids into boronic esters. Through iterative application of the process, complex chiral molecules can be synthesized. The stereoselectivity of the reaction is determined by a chiral diol incorporated in the boronic ester.

Molybdooxaziridine Catalysis: Synthesis of α‐Hydroxysulfones From Styrenes Through an ATRA Process

European Journal of Organic Chemistry, Volume 29, Issue 39, 22 October 2026.
This work has discovered that molybdooxaziridine catalysts promote the hydroxysulfonation of substituted α‐methyl‐styrenes using N‐Ts‐hydroxylamine as the nitrogen source. An atom‐transfer‐radical‐addition mechanism involving the stepwise addition of Ts and hydroxy radicals takes place.

Concerning the Problem of the Isokinetic Relationship. III. The Temperature-Dependance of the hammett Equation

, 1985
It is shown that the temperature-dependence of the Hammett equation is, in contrast to tradition, both physically and experimentally better described by means of temperature-dependent σ and temperature- independent ρ (termed ρo).
