Phosphine‐Free NNN‐Manganese(II) Catalyzed C‐alkylation of Methyl N‐Heteroarenes via Borrowing Hydrogen

Advanced Synthesis & Catalysis, Journal Year: 2024, Volume and Issue: 366(7), P. 1531 - 1537

Published: Jan. 31, 2024

Abstract Mn(II)‐catalyzed alkylations of methyl N ‐heteroarenes was reported via borrowing hydrogen strategy with alcohols as the alkylating reagent. The developed geometry‐constrained benzimidazole‐iminopyridyl ligand played a key role in promoting transformation and stablizing metal center. A wide range (aromatic, heteroaromatic aliphatic) ‐Heteroarenes could be able to apply current catalytic system, TON up 7400.

Titanium-Mediated Reduction of Carboxamides to Amines with Borane–Ammonia

Molecules, Journal Year: 2023, Volume and Issue: 28(12), P. 4575 - 4575

Published: June 6, 2023

In this study, the successful titanium tetrachloride-catalyzed reduction of aldehydes, ketones, carboxylic acids, and nitriles with borane-ammonia was extended to (deoxygenation) a variety aromatic aliphatic pri-, sec- tert-carboxamides, by changing stoichiometry catalyst reductant. The corresponding amines were isolated in good excellent yields, following simple acid-base workup.
