Electronically flexible PYA ligands for efficient palladium-catalyzed α-arylation of ketones. [PDF]

open access: yes, 2023
Palladium-catalyzed cross-coupling chemistry and in particular ketone α-arylation has been relying on a rather narrow range of supporting ligands with almost no alternatives to phosphines and N-heterocyclic carbenes.

Propiophenone 2,4-dinitrophenylhydrazone

open access: yesActa Crystallographica Section E Structure Reports Online, 2002
Crystals of the title compound, C15H14N4O4, were obtained from a condensation reaction between 2,4-di­nitro­phenyl­hydrazine and propio­phenone. The compound crystallizes in an E configuration. Within the di­nitro­phenyl ring the distances [average 1.417 (4) A] of C—C bonds ipso to the amino group are significantly longer than the average distance of 1.
