4-Bromo-3-phenylsydnone (SydnBr) reacts with complexes [Pd(PPh3)4] and [Pt(PPh3)4] at room temperature to give [MBr(Sydn)(PPh3)2] (M = Pd, Pt). Reaction of 4-chloromercurio-3-phenylsydnone (SydnHgCl) with electron-deficient olefins yields trans-isomers of 4-alkenylsydnones, (E)-SydnCHCHX (X = COMe, CO2Me, Ph, CN, carboranyl).
