    Compounds pass the smell test

    A vile-smelling but versatile class of compounds may find a role in more chemistry laboratories with the introduction of easily made, inoffensive versions. Isonitriles, chemicals characterized by a triple bond between a carbon and a nitrogen atom, are useful in many reactions. But many chemists have shunned them because of their pungency, says Michael C. […]

    Better protection

    A new molecular catalyst shortens a widely used reaction into a one-step process, with a bonus: It makes the reaction’s products into one of two possible mirror-image forms. When chemists synthesize compounds, they often add a protective group of atoms to a specific site on a molecule to prevent that site from reacting in subsequent […]
