Cationic polymerization of acenaphthylene and methyl acenaphthylenes

Polymer, 1973
Abstract Cationic polymerization of acenaphthylene was studied both by experimental methods and theoretical calculations. Very pure acenaphthylene was obtained by double sublimation and its polymerization kinetics were studied with SnCl 4 as initiator.

Ozonolysis of acenaphthylene and 1-substituted acenaphthylenes

The Journal of Organic Chemistry, 1990
The ozonolysis of title compound in carbon tetrachloride, acetonitrile, acetic acid, and trifluoroethanol revealed that the ozonide yield was much higher in reactions in protic solvents than in aprotic solvents. Such an assistance of the protic solvents on the ozonide formation was not observed in the case of the more bulky 1 ...

Tridecacyclene: A Cyclic Tetramer of Acenaphthylene

Chemistry – A European Journal, 2016
AbstractIn this manuscript, we describe the single‐step preparation of a cyclic tetramer of acenaphthylene through a Lewis acid‐catalyzed aldol cyclization of 1‐acenaphthenone. The previously unexplored cyclic tetramer material differs from the better‐known cyclic trimer, decacyclene, due to the presence of a central eight‐membered ring.

Self-assembled coordination cage as a reaction vessel: triplet sensitized [2+2] photodimerization of acenaphthylene, and [4+4] photodimerization of 9-anthraldehyde

Tetrahedron Letters, 2005
Inner cavity of Pd-nanocage has been used as a reaction vessel for performing triplet sensitized [2+2] photodimerization of acenaphthylene using water soluble xanthene dyes (Eosin Y and Rose Bengal) as sensitizers, and [4+4] photodimerization of 9 ...

ChemInform Abstract: Ozonolysis of Acenaphthylene and 1‐Substituted Acenaphthylenes.

ChemInform, 1990
AbstractThe ozonolysis of the acenaphthylenes (I) in protic solvents, e.g. methanol (II), yields a mixtures of the ozonide (III) and the peroxide (IV).

Photodimerisation of acenaphthylene in a clay microenvironment

Photochemical & Photobiological Sciences, 2003
The photochemical dimerisation of acenaphthylene in the presence of various cation-exchanged bentonite clays has been studied. While the cis-dimer is the predominant product when smaller cations are present in the clay interlayer, the presence of heavier atoms in the clay favors the trans-dimer. Synthetic anionic hydrotalcite clays are also found to be

Decomposition of Acenaphthylene by Ultrasonic Irradiation

Analytical Chemistry, 1998
Polycyclic aromatic hydrocarbons were extracted from a soil sample using ultrasound and dichloromethane-, cyclohexane-, and toluene-water mixtures. It was found that when dichloromethane is used as an extractant, acenaphthylene reacts with the solvent. Several chlorinated and oxygenated derivatives were identified.

Polymerization of acenaphthylene by BF3-Et2O

European Polymer Journal, 1971
Abstract The polymerization of acenaphthylene initiated by BF3-Et2O has been studied in ethylene dichloride and in methylene dichloride. The influence of monomer and catalyst concentrations, as well as that of the temperature, on the polymerization rate and on the polymer molecular weight has been investigated.

THE PHOTOCYCLOADDITION OF ACENAPHTHYLENE WITH TETRACYANOETHYLENE

Chemistry Letters, 1972
Abstract Irradiation of a solution of acenaphthylene and tetracyanoethylene yielded the cycloadduct. The excited singlet acenaphthylene is suggested to be the reactive species.

The activation and transformations of acenaphthylene by osmium carbonyl cluster complexes

Journal of Organometallic Chemistry, 2003
The reaction of Os 3(CO) 10(NCMe) 2 ( 1) with an excess of acenaphthylene at room temperature provided the complex Os 3(CO) 10(μ-H)(μ–η 2-C 12H 7) ( 2). Compound 2 contains a σ–π coordinated acenaphthyl ligand bridging an edge of the cluster.
