Organic Ligands

Chemistry Level 3

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 \(\alpha + \beta\)
