Preferred Label : di-π-methane rearrangement;
IUPAC definition : photochemical reaction of a molecular entity comprising two π-systems, separated by
a saturated carbon atom (a 1,4-diene or an allyl-substituted aromatic analogue), to
form an ene- (or aryl-) substituted cyclopropane.;
Scope note : the rearrangement formally amounts to a 1,2 shift of one ene group (in the diene)
or the aryl group (in the allyl-aromatic analogue) and bond formation between the
lateral carbons of the non-migrating moiety.;
Origin ID : D01745;
