"After discovering the sulfur-based bond for catalysis, called the chalcogen, two years ago, we decided to look at another category in the periodic table, pnictogen elements, which are ...

Examples abound of rings that feature multiple nitrogen atoms—the lightest of the pnictogen elements. There are triazoles, which snap together in the classic, copper-catalyzed click chemistry ...

Despite the odd name, pnictogens are pretty mundane. They are the elements in group 15 of the periodic table: nitrogen, phosphorus, arsenic, antimony, and bismuth. Elemental nitrogen is a gas, of ...
