Dithioketal Polymers Via Radical Polymerization of γ‐Dithiobutyrolactone

Angewandte Chemie, EarlyView.
γ‐Dithiobutyrolactone (DTBL) behaves like a ring‐retaining monomer in radical copolymerization with a series of conjugated monomers like styrene, t‐butyl acrylate and N,N‐dimethylacrylamide. The resulting copolymers contain controlled fractions of dithioketal linkages in their backbone, allowing chemical degradation.

Biocatalytic Synthesis of Isoxazolines Enabled by Cryptic Nitrile Oxide Formation by a Vanadium‐Dependent Chloroperoxidase

Angewandte Chemie, EarlyView.
The vanadium‐dependent haloperoxidase (VHPO) class of enzymes has been shown to catalyze cryptic nitrile oxide generation in an oxidative [3+2] cycloaddition reaction between aldoximes and alkenes to generate isoxazolines. This biotechnology has been applied to a chemoenzymatic sequence starting from aldehydes through in situ condensation with ...

Converting 1,1‐Bisborylalkanes into 1,2‐Bisborylalkanes Enabled by Iron Ligand‐to‐Metal Charge Transfer (LMCT) Photocatalysis

Angewandte Chemie, EarlyView.
1,2‐Bisborylalkanes are valuable intermediates for chemical synthesis as they could serve as a platform to generate value‐added products with two distinct functional groups at vicinal positions. A novel strategy to synthesize 1,2‐bisborylalkanes via Fe ligand‐to‐metal charge transfer (LMCT) photocatalysis is developed.
