After deciding to first tackle the barrier of transition metal catalysis, Xu Yun and others quickly changed into a set of standard lab attire.
Students who passed high school chemistry should know.
According to the periodic law of elements, people often search for catalysts in the region of transition metals.
For example, the catalyst for synthesizing ammonia is an iron catalyst.
Vanadium pentoxide is the catalyst for synthesizing sulfuric acid and nitric acid.
Ranny nickel is often used for the addition of olefins and hydrogen gas, among other things.
Why do these transition elements and compounds frequently play the role of "matchmaker"?
Let's first use layman's terms to explain a concept here:
Feedback π-bond.
When a coordination bond is formed between a transition metal atom (central atom) and a ligand.
The coordination atom provides an electron pair and fills the empty orbital provided by the central atom, forming a σ-bond in the form of a coordination bond.
