摘要:
Phenylethynyl itterbium derivative (PhC C)(2)Yb(THF)(2) reacts with tetraphenylantimony halides in tetrahydrofuran (THF) at room temperature to form triphenylantimony, phenylacetylene, benzene, and phenylethynylitterbiurn PhC CYbX(THF)(4) and itterbium YbX2(THF)(4) halides; X = Cl, Br, I. The reduction of the antimony derivative is accompanied with the generation of phenyl and phenylethynyl radicals.
