4. Classify the following reactions according to the “Essential OM Reactions Steps\" guide justify your answers. . trans-[1rCl(CO)(PPh)21+CH3Br [1rCI(CH3)(Br)(CO)(PPh3)2] . [(ns-CsHs)Co(Me)(COMe)(PPhs)] +CO [(-C5Hs)Co(CO)(PPh)] + Me C(O)

Solution

1) first reaction is the oxidative addition reaction because the Oxidation state of [PtCl4] (-2) is +2

whereas in the product the Oxidation state = +4

2) this reaction is the transmetallation reaction

Br of the Sb attached to Li whereas Me of the Li attached to Sb

3) This reaction is also oxidative addition reaction as the Oxidation state change from +1 (reactant) to +3 (product)

4) This reaction is the insertion reaction of the CO
