A one-pot procedure for preparing 2-substituted benzimidazoles directly from activated alcohols in good to excellent yields using a new Tandem Oxidation Process (TOP) is reported. The use of this methodology to prepare 2-substituted benzoxazoles and 2-substituted benzothiazoles is also described.

Ruthenium-catalyzed aromatic H/D exchange in [D4]acetic acid has been developed. By using N-heteroarenes as directing groups, both ortho and meta positions are selectively deuterated with high levels of D incorporation. Moreover, this strategy provides an alternative way to achieve meta-C-H activation.
Intramolecular C(sp3)–H Imination towards Benzimidazoles Using Tetrabutylammonium Iodide and tBuOOH

Development of sustainable and economically viable methods is challenging but desired in organic synthesis. Herein, intramolecular C(sp3)–H imination between a free amine group and N-methylene group is established using TBAI (20 mol %)-TBHP (3.0 equiv.) in DMSO which is found to be an inexpensive replacement of PhI-mCPBA in HFIP.
