# Organic Ligands

Chemistry Level pending

We wish to study vitamin $$B_{12}$$. We plan on synthesizing complex X, that can help us understand its reactions with various substrates.

Synthesizing Y : A three step process

• We start with 2-butyne and ozone to give us compound A
• A reacts with Zinc and acetic acid to give B
• B reacts with hydroxyl-amine and catalytic amount of $$H^{+}$$

Adding pyridine and ligand Y to a solution of $$CoCl_{2}$$ gives us compound X.

Let $$\alpha$$ denote the number of rings present in A and $$\beta$$ denote the number of unpaired electrons in compound X.

Find the value of $$\alpha + \beta$$
