Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 175136-62-6, is researched, SMILESS is FC(C1=CC(C(F)(F)F)=CC(P(C2=CC(C(F)(F)F)=CC(C(F)(F)F)=C2)C3=CC(C(F)(F)F)=CC(C(F)(F)F)=C3)=C1)(F)F, Molecular C24H9F18PJournal, Article, Organic Letters called Iridium-Catalyzed Direct Tetraborylation of Perylene Bisimides, Author is Teraoka, Takuro; Hiroto, Satoru; Shinokubo, Hiroshi, the main research direction is iridium catalyzed borylation perylene bisimide pinacolato diboron regioselectivity; crystal mol structure tetraborylated perylene bisimide; mol structure calculation tetrahydroxy tetramethoxy perylene bisimide.Application In Synthesis of Tris(3,5-bis(trifluoromethyl)phenyl)phosphine.
Treatment of perylene bisimides (PBIs) with bis(pinacolato)diboron in the presence of an iridium catalyst provides tetraborylated PBIs at 2,5,8,11-positions in good yields with perfect regioselectivity. The planar structure of the perylene core has been confirmed by x-ray diffraction anal. Oxidation of tetraborylated PBI with hydroxylamine hydrochloride affords tetrahydroxy PBI in excellent yield, which exhibits a substantially blue-shifted absorption spectrum due to an intramol. hydrogenbonding interaction between carbonyl and hydroxy groups.
