Everything Matters | Boron | Paul Stepahin | Exploratorium
Join Paul Stepahin for a presentation about quantum mechanics and the elements.Boron is complicated. Elusive. Tough. Created in collisions between cosmic rays and interstellar dust, pure boron may be found in meteoroids, but not naturally on Earth. And yet this relatively uncommon element

Boron Aldol Reaction - Organic Chemistry, Reaction Mechanism
An introduction to diastereoselective aldol reactions using soft enolisation techniques to selectively synthesise one enolate geometry and a Zimmerman-Traxler transition state model to form the new C-C bond and two new stereogenic centres (stereocentres) at the same time. #organicchemistr

Make Hydrobromic Acid Revisited 2018
We show how to make hydrobromic acid. Hydrobromic acid is the bromine analogue of hydrochloric acid. While too expensive to use as much as hydrochloric acid, it's often used when the bromine element itself is needed. For example a major use is the synthesis of organobromine compounds like
