After deciding to tackle the barrier of transition metal catalysis first, Xu Yun and the others quickly changed into a set of standard lab coats.
Anyone who passed high school chemistry should know this.
According to the periodic table, people often look for catalysts among the transition metals.
For example, the catalyst for ammonia synthesis is an iron catalyst.
Vanadium pentoxide is the catalyst for synthesizing sulfuric acid and nitric acid.
Raney nickel is commonly used for the addition of olefins and hydrogen, etc.
Why do these transition elements and their compounds often play the role of "matchmaker"?
Let me explain a concept to you in plain language first:
Backbonding π bond.
When a transition metal atom... that is, a central atom and its ligands form a coordination bond.
The coordinating atom donates a lone pair of electrons to fill the empty orbital provided by the central atom.
Thus, a sigma bond is formed via a coordination bond.
Sometimes,
