The reaction of 2-methylfuran with methyl acrylate in the presence of Pd(OAc)2 gave unusual products such as 1,1′-bis(5-methyl-2-furyl)ethane (22%) and methyl 3,3′-bis(5-methyl-2-furyl)propionate (10%) along with the usual aromatic substitution product. This is a marked contrast to the reaction of furan with olefins.
在Pd(OAc)2的存在下,
2-甲基呋喃与
甲基丙烯酸甲酯的反应产生了不寻常的产物,例如1,1′-双(5-甲基-2-
呋喃基)
乙烷(22%)和3,3′-双(5-甲基-2-
呋喃基)
丙酸甲酯(10%),以及常见的芳香族取代产物。这与
呋喃与烯烃的反应形成了鲜明的对比。
