Migratory insertion of isocyanide into a ketenyl–tungsten bond as key step in cyclization reactions

Treatment of the side-on tungsten alkyne complex of ethinylethyl ether [Tp*W(CO)(2)(η(2)-C,C′-HCCOCH(2)CH(3))](+) {Tp* = hydridotris(3,4,5-trimethylpyrazolyl)borate} (2a) with n-Bu(4)NI afforded the end-on ketenyl complex [Tp*W(CO)(2)(κ(1)-HCCO)] (4a). This formal 16 ve complex bearing the prototype...
