Question

Organocatalytic syntheses of benzoxazoles and benzothiazoles using aryl iodide and oxone via c-h functionalization and c-o/s bonds formation

Answer 1

Here, we report a one-step solvothermal synthesis of TiO2-reduced graphene oxide (TiO2-xRGO) composite catalysts using a mild reducing agent, dimethylformamide (DMF). Nanoscale TiO2 particles in the size range of 4–9 nm were formed on the reduced graphene sheets.

Answer 2

An organocatalytic protocol for the syntheses of 2-substituted benzoxazoles and benzothiazoles is described from alkyl-/arylanilides and alkyl-/arylthioanilides ..
