Transition metal-germylene complexes of the type X2GeM(CO)5·TMF (M Cr, W; X F, Cl) react with nitrones by nucleophilic exchange at gernamium to form new stable adducts. The structure of such a compound was determined by single crystal X-ray diffraction, and its bonding is discussed in terms of the resulting structural parameters.

Tertiary allylic nitro compounds, bearing an acetate or a mesylate in β position smoothly undergo a reductive elimination to give conjugated 1,3 dienes when treated with chromous acetate/ 2,2′-dipyridyl in DMF at 110–120°C.
