Catalytic conversion of 4-tert-butylphenol in hydrogen peroxide solutions in the presence of titanium oxide compounds and titanosilicates

The catalytic conversion of 4-tert-butylphenol (TBP) in hydrogen peroxide solutions in the presence of titanium oxide samples with different phase compositions and crystalline and amorphous titanosilicate samples has been studied. It has been shown that microporous crystalline titanosilicate TS-1 exhibits low activity in the TBP conversion owing to steric restrictions to the diffusion of the substrate molecules to catalytically active sites. The samples of titanium oxide compounds and mesoporous titanosilicates exhibit similar activity, while the selectivity of the latter for 4-tert-butylcatechol (TBC) is higher. The effect of the mesoporous titanosilicate concentration in the reaction mixture and the test temperature and duration on the TBP conversion and the TBC selectivity has been determined.

Cu-Catalyzed Couplings of Heteroaryl Primary Amines and (Hetero)aryl Bromides with 6-Hydroxypicolinamide Ligands

A family of 6-hydroxypicolinamide ligands have been identified as effective supporting ligands for Cu-catalyzed couplings of heteroaryl bromides and chlorides with heteroaryl primary amines. The C-N couplings are carried out at 80-120 °C in DMSO or sulfolane using K2CO3 or K3PO4 as the base with 2-10 mol % CuI and supporting ligand. The strength of the base was found to have an impact on the chemoselectivity and rate. The use of K2CO3 as the base enabled selective C-N coupling of aryl bromides over aryl chlorides with 2-5 mol % Cu at 80-120 °C. With K3PO4 as the base, aryl chlorides are capable of undergoing C-N coupling, though 5-10 mol % Cu is required at 120-130 °C. Members of the ligand family are straightforward to prepare in one step from 6-hydroxypicolinic acid and the corresponding anilines.

Reductive Cleavage of C—O Bond in Model Compounds of Lignin

A simple protocol for reductive cleavage of C—O bond in diaryl and aryl methyl ethers was reported, in which NaH served as a reducing agent and KOtBu as a base and a radical initiator. The combination of NaH and KOtBu displayed high efficiency for reductive cleavage of C—O bond in diaryl and aryl ethers (e.g., dibenzofuran, diphenyl ether, anisole) without the hydrogenation of the aryl rings, in the absence of any other catalysts or ligands at 140 °C, producing corresponding arenes and phenols. It was indicated that the reaction was under a radical mechanism.
