WebDecide which of the two complexes (a) W (CO) 6 or (b) IrCl (PPh 3) 2 (CO) should undergo the fastest exchange with 13 CO. Justify your answer. First, draw the structures of each complex: W (CO) 6 is an 18 electron complex, so will be rather unreactive to either associative or dissociative routes.

The closely related IrBr(CO)(PPh3)2 was described in 1959 by Maria Angoletta, who prepared the complex by the treating IrBr(CO)2(p-toluidine) with PPh3 in acetone solution. In 1957, Linda Vallerino had reported RhCl(CO)(PPh3)2.
