Bacher, Emily P. published the artcileA Phosphine-Mediated Dearomative Skeletal Rearrangement of Dianiline Squaraine Dyes, Synthetic Route of 27292-49-5, the publication is Organic Letters (2021), 23(8), 2853-2857, database is CAplus and MEDLINE.
A phosphorus(III)-mediated dearomatization of ortho-substituted dianiline squaraine dyes results in an unusual skeletal rearrangement to provide exotic, highly conjugated benzofuranone and oxindole scaffolds bearing a C3 side chain comprised of a linear conflagration of an enol, a phosphorus ylide, and 2,4-disubstituted aniline. Employing exptl. and computational anal., a mechanistic evaluation revealed a striking dependence on the acidity of the aniline ortho substituent. Notably, the rearrangement adducts underwent rapid and complete reversion to the parent squaraine in the presence of a Bronsted acid.
