Identifying the True Catalyst: A Mn(II) Salt versus Mn(II) Complexes in Epoxidation with m‐Chloroperbenzoic Acid

European Journal of Organic Chemistry, EarlyView.
During the investigation of the reactivity of three Mn complexes, Mn(ClO4)2 shows higher reactivity toward styrene epoxidation, indicating that ligand coordination inhibits the reactivity of the manganese center. Raman spectroscopy provides mechanistic insight: monitoring alkene epoxidation and consumption of the oxidant over time, the true nature of ...

Enantioselective Desymmetrization of Bisphenol Derivatives by Organocatalytic Sulfonylation

European Journal of Organic Chemistry, EarlyView.
An efficient organocatalytic strategy involving the desymmetrization–sulfonylation of bisphenols is introduced for the synthesis of chiral 1,1‐diarylalkanes. A chiral thiourea catalyst enables the selective sulfonylation of one hydroxyl group with a sulfonyl chloride in a CHCl3/H2O system under basic conditions, affording the reaction products with ...

Multistep Reactions Initiated by Amine‐Based Organometallic Methods

European Journal of Organic Chemistry, EarlyView.
The advent of C–H activation and other organometallic methodologies making use of transient directing groups or free amines themselves for the elaboration of amine substrates provides unique access to cascade‐type reactions that can generate significant molecular complexity in one pot. The pursuit of atom‐ and step‐economical pathways to access complex

Room‐Temperature Direct Homolysis of Csp3─H Bond via Catalyst‐Free Photoexcitation

Exploration, EarlyView.
In the absence of catalysts and additives, under only ambient temperature and light conditions, organic compounds undergo vibrational relaxation processes after photon excitation, followed by direct C‐H cleavage to generate hydrogen radicals and carbon radicals.
