Triaryl- and triheteroarylmethanes have been synthesized in very good yield under solvent-free conditions from differently substituted aldehydes and 2-methylfuran or methoxybenzene in the presence of Yb(OTf)3 as catalyst. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
在无溶剂条件下,在 Yb(OTf)3 作为催化剂的存在下,由不同取代的醛和 2-甲基呋喃或甲氧基苯以非常好的收率合成了三芳基甲烷和三杂芳基甲烷。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
