Organic Ligands

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 $\alpha + \beta$
