Web2 via a tetrathionate intermediate ( O 3S-S-S-SO3). The ZVS is deposited as granules, from which it can later be metabolized by sulfur dioxygenases (SdoA/SdoB) via oxidation to sulfite (SO3 2), which is subsequently spon-taneously oxidized to SO4 2. Note that not all pathway intermediates have been displayed. WebReacting Tertiary Halogenoalkanes with Cyanide Ions The facts of the reaction are exactly the same as with primary halogenoalkanes. If the halogenoalkane is heated under reflux with a solution of sodium or potassium cyanide in ethanol, the halogen is replaced by -CN, and a nitrile is produced. For example:
