摘要:
Treatment of a MeOH solution of trans-[FeBr2(depe)(2)] (depe - Et2PCH2CH2PEt2) with HC=CC6H10OH or HC=C(CH2)(n)OH (n = 1 or 2), in the presence of NaBPh4. forms the cyclic allenylidene trans-[FeBr(=C=C=C6H10)(depe)(2)][BPh4] or the alkyne trans-[FeBr{eta(2)-HC=C(CH2)(n)OH}(depe)(2)][BPh4] (n = 1 or 2) complexes, respectively.
