Synthesis and Characterization of Transition Metal Complexes Supported by Phosphorus Ligands Obtained Using Hydrophosphination of Cyclic Internal Alkenes

Molecules
The design and study of rich, bulky phosphorus ligands is a key area of research for homogeneous catalysis. Here, we describe an original strategy using a hydrophosphination reaction to produce phosphines of interest for coordination chemistry and ...

Comparison of PCBs and PAHs levels in European coastal waters using mussels from the Mytilus edulis complex as biomonitors

Oceanologia, 2015
Mussels from the Mytilus edulis complex were used as biomonitors for two groups of organic pollutants: polychlorinated biphenyls (PCBs, congeners: 28, 52, 101, 118, 138, 153 and 180) and polycyclic aromatic hydrocarbons (PAHs, naphthalene, acenaphthylene,

Crystal structure of 8-[7,8-bis(4-chlorobenzoyl)-7H-cyclopenta[a]acenaphthylen-9-yl]naphthalene-1-carboxylic acid

Acta Crystallographica Section E: Crystallographic Communications, 2015
The title compound, C40H22Cl2O4, was formed by a Michael–Aldol domino reaction sequence, which coupled acenaphthenequinone with 4-chloroacetophenone in the presence of KOH in methanol.

Concentration dependence of the steric course of bromine addition to acenaphthylene. A product and kinetic study

, 1997
The ratios of Z- to E-1,2-dibromo-1,2-dihydroacenaphthylene obtained in the bromination of acenaphthylene in chlorinated solvents have been determined by NMR as a function of the reagents concentrations.

Mechanism of Photodimerization of Acenaphthylene

, 2016
The mechanism of photodimerization of acenaphthylene (ACN) has been investigated in order to elucidate the roles of the singlet and the triplet excited states of ACN in the formation of the Z- and E-dimers in several solvents.

Dye-sensitized solar cells with 13% efficiency achieved through the molecular engineering of porphyrin sensitizers [PDF]

, 2014
Dye-sensitized solar cells have gained widespread attention in recent years because of their low production costs, ease of fabrication and tunable optical properties, such as colour and transparency. Here, we report a molecularly engineered porphyrin dye,

A Regioselective Multicomponent Approach for the Synthesis of Novel 2-Acetyl-4-phenylquinoline Designed Monospiro-Pyrrolidine and Thiapyrrolizidine Hybrids

Heteroatom Chemistry
A convenient approach for the synthesis of 2-acetyl-4-phenylquinoline designed monospiro-pyrrolidine/thiapyrrolizidine hybrids has been achieved via a 1,3-dipolar cycloaddition reaction of various azomethine ylides derived from isatin/acenaphthylene-1,2 ...

Construction of acenaphthylenes via C−H activation-based tandem penta- and hexaannulation reactions

Nature Communications
Acenaphthylene-containing polycyclic aromatic hydrocarbons (AN-PAHs) are noteworthy structural motifs for organic functional materials due to their non-alternant electronic structure, which increases electron affinity.

The Mechanism of Formation of Acenaphthylene on Pyrolysis of 8-Methylcyclobuta[a]naphthalene-1,2-dione

, 1989
Flash vacuum pyrolysis of the l-13C labelled title dione (13) gives acenaphthylene labelled predominantly at C4 (65.9%) and C1 (27.6%). This is in accord with the intermediacy of the (labelled) acyloxycarbene (5), the lactone (6) and the carbene ...
