Photolysis of [Mo(CO)3(cp)}2] with Se2(C6F5)2 in toluene yields [Mo(SeC6F5)(CO)3(Cp)]8a, and the thermal reaction of [MoCl(CO)3(Cp)] with two equivalents of Tl(SeC6F5) in diethyl ether gives the thallium complex Tl[Mo(SeC6F5)2(CO)2(Cp)]9, via complex 8a isolated as a by-product. Reaction of [WBr3(CO)2(Cp)] with three equivalents of Tl(SeC6F5) produces [W(SeC6F5)3(CO)(Cp)]12, with [W(SeC6F5)(CO)3(Cp)]8b as
