The researchers also found that doubly hydrochlorinating a triple bond with this reaction gives a product with each chlorine bound to a different carbon atom, whereas the classic method would ...

Nitrogen atoms can form three covalent bonds, so a triple bond forms between them. The structure of nitrogen is N≡N, showing that it has three shared pairs of electrons.

Electrochemical reactions for organic synthesis typically ... aryl C(sp2)–H bonds by cleavage and recombination of C–C triple bonds with the participation of nitrous acid esters.
