4-[2-(5-Ethyl­pyridin-2-yl)­ethoxy]­benz­aldehyde oxime

The title compound, C₁₆H₁₈N₂O₂, is a key intermediate for the synthesis of biologically active novel heterocycles, e.g. isoxazolines and isoxazoles. Geometric parameters of the mol­ecule are in the usual ranges. The crystal packing is stabilized by an O—H...N hydrogen bond.

N,N-Bis(2-cyano­eth­yl)-p-toluene­sulfonamide

In the title compound, C₁₃H₁₅N₃O₂S, the geometric parameters are in the normal ranges. The amide N atom is coordinated in an almost trigonal-planar fashion.
