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 […]

Tricky Transformation: Bubbling gases tighten, then loosen, the grip of novel molecules on grime
New compounds make oil mix with water, or not, depending simply on which gases are bubbled through the water.
