In this paper, we designed and synthesized a new type of cyclic carbonates, allenylethylene carbonates (AECs). With AECs as reactive precursors, we developed palladium-catalyzed (3+3) annulation of AECs with nitrile oxides. Various AECs worked well in this reaction under mild reaction conditions. A variety of 5,6-dihydro-1,4,2-dioxazine derivatives with allenyl quaternary stereocenters can be accessed in a facile manner in high yields (≤98%).
Reductive condensation of trichloromethylarenes with hydroxylamine and hydrazines in pyridine

The interaction of trichloromethylarenes with hydroxylamine in pyridine involves the reductive oximation of aryltrichloromethanes. Further transformations of the oximes in the reaction course can result in the formation of nitriles or 3,5-diaryl-1,2,4-oxadiazoles as final products. The conversion depth depends on reaction conditions and structures of trichloromethyl-arenes. When hydrazines used instead of hydroxylamine, respectivebenzaldehyde hydrazones or azines are obtained.
