| Ytterbium phenylethynyl cuprate {[(PhC?C)
3Cu]Yb(THF)
2}
2 reacts with benzyl chloride, methyl iodide and triphenylmethyl chloride in tetrahydrofuran (THF) at 20-90°C leading to the elimination of phenylethynylcopper and formation of polyfunctional hydrocarbon and halogenides PhC?CYbCl(I), YbCl
2 (YbI
2). A discussion of the reaction mechanism is presented. |
