Diels-alder reaction of isobenzofurans/cyclopentadienones with tetrathiafulvalene: Preparation of naphthalene, fluoranthene, and fluorenone derivatives
Diels-Alder reaction of 1,3-diarylbenzo[c]furan/cyclopentadienone with TTF followed by triflic acid mediated cleavage of the resulting adducts led to the formation of the respective 1,4-diaryl substituted naphthalenes, fluoranthenes, and fluorenones. The photophysical properties of representative diaryl-substituted hydrocarbons are also reported.

The strategy to improve thermal and optical properties of diphenylfluoranthene based on silicon-cored derivatives
A series of novel silicon-cored diphenylfluoranthene derivatives was synthesized in this paper to realize efficient solid-state emission. These silicone-cored diphenylfluoranthene derivatives show better fluorescent properties in the solid state than diph
A silicon-cored fluoranthene derivative as a fluorescent probe for detecting nitroaromatic compounds
Two fluoranthene derivatives, nonsilicon-cored 7,10-diphenylfluoranthene (DF) and silicon-cored bis(7,10-diphenylfluoranthen-8-yl)diphenylsilane (BDS), were synthesized via the Knoevenagel/Diels-Alder method. The thermal properties and fluorescence quench
Synthesis of fluoranthenes and indenocorannulenes: Elucidation of chiral stereoisomers on the basis of static molecular bowls
Cycloaromatization of a peri diyne with an external alkyne provides a general route to indenofused polynuclear aromatics. Fluoranthenes 9 (or 13) are easily accessible in good to excellent yields (75-99%; 18 examples) from the reaction of symmetric (or as

Formal [(2+2)+2] and [(2+2)+(2+2)] nonconjugated dienediyne cascade cycloadditions
(Chemical Equation Presented) Fluoranthene 2 and heptacycle 3 are easily accessible from the reaction of diyne 1 and norbornadiene (NBD) in the presence of the rhodium catalyst. The unusual [(2+2)+(2+2)] adduct 3 was confirmed by the X-ray crystal structu

Imposing curvature on a polyarene by intramolecular palladium-catalyzed arylation reactions: A simple synthesis of dibenzo[a,g]corannulene
(Matrix Presented) Palladium catalysis has been found to offer an effective solution-phase alternative to gas-phase flash vacuum pyrolysis as a method for converting the planar ring system of 7,10-di(2-bromophenyl)fluoranthene (4) to that of the C28

SYNTHESIS OF ORGANOSILANE CONTAINING FUSED AROMATIC RINGS BY DIELS-ALDER REACTION
Organosilane I containing substituted fluoranthene group has been synthesized by Diels-Alder reaction of vinylmethyldichlorosilane with acecyclone.The structure of I has been determined by elemental analysis, 1H-NMR and IR.
PERICYCLIC TRANSFORMATIONS OF TETRACYCLO2,903,8>TRIDECA-4,6,11-TRIENES, AND FORMATION OF DIHYDROSEMIBULLVALENES BY THERMAL INTRAMOLECULAR?4a+?2a>CYCLOADDITION IN SUBSTITUTED CYCLOOCTATRIENES
Cyclopentadienones react with certain cyclobutene dienophiles to give the anticipated carbonyl bridge adducts; these, on relatively mild thermolysis, yield dihydrosemibullvalene derivatives by a novel sequence including cheletropic loss of carbon monoxide, electrocyclic ring opening of immediate substituted bicyclooctadienes, and intramolecular ?4a + ?2a>cycloaddition of the derived cyclooctatrienes.Other pericyclic reactions of compounds related to those of the title compounds are also discussed.
