4-(p-Tolylamino)benzaldehyde [PDF]

Acta Crystallographica Section E Structure Reports Online, 2010
In the title compound, C(14)H(13)NO, the dihedral angle between the aromatic rings is 66.08 (9)°. Chains are formed along the b axis through inter-molecular N-H⋯O hydrogen bonds. The crystal structure is further stabilized by C-H⋯π inter-actions.

Easy access to medium-sized lactones through metal carbene migratory insertion enabled 1,4-palladium shift

Nature Communications, 2020
Transannular construction of medium-sized lactones is entropically unfavoured. Herein, the authors describe a strategy for valuable medium-sized lactone synthesis from available benzaldehydes by selective C-H bond functionalization via palladium carbene ...

Bio-inspired iron-catalyzed oxidation of alkylarenes enables late-stage oxidation of complex methylarenes to arylaldehydes

Nature Communications, 2019
Oxidation of toluenes to benzaldehydes is usually accompanied by overoxidation products. Here, the authors report an iron-catalysed aerobic oxidation of methylarenes to benzaldehydes with high yields and selectivities, even in presence of boronic acid ...

Syn-selective silicon Mukaiyama-type aldol reactions of (pentafluoro-λ6-sulfanyl)acetic acid esters with aldehydes

Beilstein Journal of Organic Chemistry, 2018
Aldol reactions belong to the most frequently used C–C bond forming transformations utilized particularly for the construction of complex structures. The selectivity of these reactions depends on the geometry of the intermediate enolates.
