Tertiaryalcohols can be dexygenated in a radical chain reaction based on their mixed oxalate esters with N-hydroxy-2-thiopyridone, these esters being obtained directly from the alcohols and chloride etc, or via their trimethylsilyl derivatives.
Toluene radical anion generated from potassium metal/dicyclohexano-18-crown-6/toluene system has been proved to be highly effective for reductive decyanation reaction of primary, secondary and tertiary cyanides.

Primary, secondary, and tertiary aliphatic or alicyclic isocyanides are smoothly reduced under radical conditions using tri-n-butylstannane to the corresponding hydrocarbons. The relative ease of reduction is tertiary > secondary > primary. Aromatic isocyanides are not reduced under these conditions. The reduction of isothiocyanates (or isoselenocyanates) by tri-n-butylstannane also affords hydrocarbons
