Solvent Free Conditions

Grinding of various electron-deficient dienophiles with diverse dienes in a pestle and mortar for 1–15 minutes afforded the corresponding Diels–Alder adducts in quantitative yields under catalyst-free and solvent-free conditions, without the necessity for any purification steps.

Degree Of Similarity

A series of phenyl-substituted bis(isobenzofuran)s in which the furan moieties are linked by 1,3-phenylene, 1,4-phenylene, or 4,4′-biphenylene linkers have been prepared in only two steps. They are comparable to diphenylisobenzofuran in their absorption and luminescent properties, their electrochemistry, and their reactivity. Their degree of similarity to diphenylisobenzofuran was found to depend significantly on the nature of the linking group. Diels–Alder reaction of the title compounds and subsequent aromatization gave very rapid access to penta- or hexa-aryl products.
