Six‐membered ring fused furans containing a tetrasubstituted tertiary carbon were prepared in an unprecedented one‐pot BODIPY‐catalyzed domino photooxygenation/reduction process. A series of functionalized furans was synthesized from readily available 2‐alkenylphenols and mechanistic studies were performed to account for the domino photosensitized oxygenation.

The present invention provides a method for producing an encapsulated product in which a core substance having an electric charge on its surface is coated with a wall material comprising a polymer as a main component, the production method comprising at least the following steps (1) to (4): (1) a step of adding an ionic polymerizable surfactant A containing an ionic group having the opposite electric charge to the electric charge on the surface of the core substance, a hydrophobic group and a polymerizable group to an aqueous solvent containing the core substance, followed by mixing, thereby adsorbing the ionic polymerizable surfactant A to the surface of the core substance; (2) a step of adding, after said step (1), an ionic polymerizable surfactant B containing an ionic group having the same or opposite electric charge to the electric charge on the surface of the core substance, a hydrophobic group and a polymerizable group, followed by mixing; (3) a step of adding, after said step (2), a hydrophobic monomer and an oil-soluble polymerization initiator, followed by mixing; and (4) a step of polymerizing the ionic polymerizable surfactant A, the ionic polymerizable surfactant B and the hydrophobic monomer to form the polymer. Also, an encapsulated product obtained by this production method is disclosed.

Disclosed are a method for preparing a complex oxide particle composition, the so-prepared particle composition and its use as electrode material. This composition comprises complex oxide particles having a non powdery conductive carbon deposit on at least part of their surface. Its method of preparation comprises nanogrinding complex oxide particles or particles of complex oxide precursors, wherein an organic carbon precursor is added to the oxide particles or oxide precursor particles before, during or after nanogrinding, and pyrolysing the mixture thus obtained; a stabilizing agent is optionally added to the oxide particles or oxide precursor particles before, during or after nanogrinding; and the nanogrinding step is performed in a bead mill on particles dispersed in a carrier solvent.
