Cu2+ – assisted photomethylation of fluoride in dilute acetic acid medium is suggested to occur by radical halogen atom transfer, with Cu(ii) acting in a catalytic capacity.

Radiochemical Yields

Radiochemical reactions of 82Br, 128I, and 56Mn have been studied in neutron-irradiated BrMn(CO)5 and IMn(CO)5. The parent compounds were found to contain 49 and 28% of the 82Br and 128I, but only 6 and 10% of the 56Mn, respectively. The dimeric [XMn(CO)4]2 accounted for 28% of the 82Br, but only about 2% of the 56Mn. Some 56Mn2(CO)10 was also found. The radiochemical yields of several products were found to increase substantially on thermal treatment of the target material.Reaction pathways are suggested which can account for the thermal effects, which involve halogen atom transfer and carbonyl transfer in the solid.
