Hagens, Graham; Wasacz, John P.; Joullie, Madeleine; Yates, Peter published the artcile< Photolysis of 2,2,5,5-tetramethyldihydro-3-furanone>, SDS of cas: 5455-94-7, the main research area is furanones photolysis; photolysis furanones.
The photolysis of 2,2,5,5-tetramethyldihydro-3(2H)-furanone in MeOH gives Me 3-isopropoxy-3-methylbutanoate, Me 3-methyl-2-butenoate, iso-Pr 3-methyl-2-butenoate, Me 3-methyl-3-butenoate, and iso-PrOH. These products are all considered to arise via the ketene formed by Norrish type I cleavage of the dihydrofuranone followed by intramol. H abstraction. Corroboration for this view is that photolysis of 2,2,5,5-tetramethyldihydro-3(2H)-furanone-4-d2 in MeOH gives Me 3-(isopropoxy-2-d)-3-methylbutanoate and Me 3-methyl-2-butenoate-2-d.
Journal of Organic Chemistry published new progress about Photolysis. 5455-94-7 belongs to class tetrahydrofurans, and the molecular formula is C8H14O2, SDS of cas: 5455-94-7.
