- The tin–tin triple bond in the distannyne Ar iPr4SnSnAr iPr4, Ar iPr4 = C6H3-2,6(C6H3-2,6-iPr2)2, undergoes reversible cleavage in deuterated toluene to afford two :SṅAr iPr4 radicals in solution as shown by 1H nuclear magnetic resonance and electron paramagnetic resonance spectroscopy. Variable temperature data afforded an enthalpy of dissociation of ΔH diss = 17.2 ± 1.7 kcal mol–1 via van‘t Hoff analysis.
