A palladium(II)-catalyzed directacylation of acetophenone N-Boc hydrazones with aldehydes via C–H bond activation is described. This protocol provides direct access to a range of 1,2-diacylbenzenes, which are useful precursors to construct biologically interesting and pharmaceutically important compounds.

AbstractThe electron impact mass spectra of the new synthesized dioximes of o‐diacyl benzenes (2) are reported. In addition to the molecular ion, characteristic peaks appear at values corresponding to the [M − OH] +, [M − NOH]+ and [M − NHOH]+ ions. No initial dehydration of the molecular ion has been observed.
