A University of California – Berkeley team has now cracked the strongest of carbon-hydrogen bonds, those on a molecule’s terminal carbon. The C-H bond – 2/3rds of all bonds in hydrocarbons – has defied chemists’ attempts to open it up and add new chemical groups. The reaction catalyst is an iridium atom to break the […]

UCLA chemists have developed a new technique to convert carbon-hydrogen bonds into carbon-carbon bonds using catalysts made of silicon and boron, both abundant and inexpensive elements. When scientists develop the chemical formulas for new products such as fuels and medications, they often must first create molecules that haven’t previously existed. A basic step toward creating […]

Emory University chemistry scientists have demonstrated the ability to selectively functionalize the unreactive carbon-hydrogen (C-H) bonds of an alkane without using a directing group, while also maintaining virtually full control of site selectivity and the three-dimensional shape of the molecules produced. First, a little background. Alkanes are the simplest of organic molecules, consisting only of […]
