How does boron get its name?
Let me explain - the name boron comes from the mineral borax, which is a salt of the a really uninspiring acid called boracic acid. You can buy it from any pharmacist, and it's a mildly acidic antiseptic, and it essentially comprises a boron atom attached to three OH groups. And here's the surprise - you can fairly easily swap one OH for an aryl group, and you generate an aryl boronic acid capable of coupling to a whole range of aryl halides using palladium catalysis. This was a long sought-after process that many had thought impossible in high yield, until a chemist called Suzuki (hence the motorbike connection) found that boron could solve the trick.
