    Reference: OCR

    The key step that lengthens a carbon chain during synthesis, joining two fragments so the product has more carbon atoms than the starting material.
    OCR · Carbon–carbon bond formation
    The carbon–halogen bond breaks and a new carbon–carbon bond forms, so the carbon chain lengthens by one carbon atom and a nitrile is produced.
    OCR · Carbon–carbon bond formation
    The carbon chain is lengthened by one carbon, so this is a useful carbon–carbon bond-forming step.
    OCR · Carbonyl compounds
