The Reaction on 2-Methylfuran with Methyl Acrylate Unusual Formation of 1,2'-Bis(5-methyl-2-furyl)ethane and Methyl 3,3'-Bis(5-methyl-2-furyl)propionate

Maruyama, Osamu,Fujiwara, Yuzo,Taniguchi, Hiroshi

, p. 2851 - 2852 (1981)

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 (22percent) and methyl 3,3'-bis(5-methyl-2-furyl)propionate (10percent) along with the usual aromatic substitution product.This is a marked contrast to the reaction of furan with olefins.
