Experimental support for planar pseudopericyclic transition states in thermal cheletropic decarbonylations

(Chemical Equation Presented) Low-temperature crystal structures of three pyrrolediones (3-5) and a furandione (9) were obtained and compared to structurally related compounds that cannot undergo decarbonylation. Systematic trends in bond lengths and angl

Five-Membered 2,3-Dioxo Heterocycles: XLV. Thermolysis of 5-Aryl-4-phenyl-2,3-dihydrofuran-2,3-diones in the Absence of Other Partners and in the Presence of Carbonyl Compounds

Aroyl(phenyl)ketenes generated by thermolysis of 5-aryl-4-phenyl-2,3- dihydrofuran-2,3-diones undergo [4+2]-cyclodimerization to 3-aroyl-6-aryl-3,5- diphenyl-3,4-dihydro-2H-pyran-2,4-diones. Heating of the latter leads to rearrangement with formation of 4-aroyloxy-6-aryl-3,5-diphenyl-2H-pyran-2-ones. Thermolysis of 5-aryl-4-phenyl-2,3-dihydrofuran-2,3-diones in the presence of carbonyl compounds yields 6-aryl-5-phenyl-4H-1,3-dioxin-4-ones.

FIVE-MEMBERED 2,3-DIOXOHETEROCYCLES XXVII. 4,5-DIPHENYL-2,3-DIHYDRO-2,3-FURANDIONE. SYNTHESIS AND REACTIONS WITH AMINO COMPOUNDS

4,5-Diphenyl-2,3-dihydro-2,3-furandione reacts with amines and hydrazines to form the amides and hydrazides of 2,3-dioxo-3,4-diphenylbutyric acid.The products exist preferentially in the form of the respective five-and six-membered ring isomers and readil
