Abstract

We have synthesized sterically strained conjugated systems containing a trisubstituted furan ring. We have used X-ray diffraction to study the three-dimensional structure of 5-dimethylamino-2,4-bis[(2,2-dimethyl-4,6-dioxo-1,3-dioxan-5-ylidene)methyl]furan. We have shown that such sterically strained systems undergo nonclassical deformations with distortion of mainly bond angles, but without loss of planarity.
