Despite the the fact that furfural was discovered in 1832 ^[1] , Gianluca ^[2] and his co-authors found that ..

there is still much to be discovered, especially with regard to the complex set of side and loss reactions seemingly involving largely unknown reaction intermediates.

In the January 2014 issue, Green Chemistry presents a critical review of "both the mechanistic and kinetic aspects of furfural formation from pentoses in aqueous acidic media have been reviewed. Based on the reviewed literature, a comprehensive reaction mechanism has been
