2. The ligand is the dihydrogen molecule H2

A particularly interesting case is the attachment of the hydrogen molecule H 2 as such. This situation was discovered by Kubas.

Let's start by activating tungsten carbonyl through the action of cycloheptatriene, which replaces three molecules of CO :

[W(CO) 6 ] + C 7 H 8 → [W(CO) 3 (C 7 H 8 )] + 3 CO

The tungsten environment remains at 18 electrons. The action of a phosphine whose R groups are very bulky, such as the isopropyl...
