Photodimers of fumaric and maleic acid derivatives; final report

Abstract

Direct irradiation of dimethyl fumarate in the solid state was shown to afford a single dimer cis,trans,cis-1,2,3,4-tetracarbomethoxycyclo butane. Isomerization of this dimer to the thermodynamically more stable trans,trans, trans tetraester is readily achieved thermally. Simi lar results were obtained with fumaronitrile and maleic anhydride. Photodimers of fumaric acid derivatives have provided ideal precursors for the synthesis of the novel nonbenzenoid sys tem tetramethylenecyclobutane. Of these, di methylfumarate dimer proved most practical from a synthetic standpoint. (Author)
