Usage

General Description

2,3-dihydro-1H-benz[e]indene, also known as naphthalene, is a polycyclic aromatic hydrocarbon (PAH) consisting of two fused benzene rings. It is a colorless, flammable solid with a strong, mothball-like odor. Naphthalene is commonly used as a moth repellent and as a precursor to other chemicals. It is also found in cigarette smoke, automobile exhaust, and industrial emissions. Naphthalene is considered to be toxic to humans, particularly with prolonged exposure, and has been classified as a possible human carcinogen. It is known to cause respiratory problems and can affect the central nervous system. Overall, naphthalene is a potentially hazardous chemical and its use and exposure should be carefully monitored.

Platinum-catalyzed aromatization of enediynes via a C-H bond insertion of tethered alkanes

PtCl2 (5 mol %) is an effective catalyst for aromatization of enediynes via a C-H bond insertion of tethered alkanes. The reaction mechanism of this cyclization is proposed to involve platinum-.T-alkyne intermediates. This cyclization works not only for terminal alkynes but also for internal alkynes.

Sequential Suzuki-Miyaura Coupling/Lewis Acid-Catalyzed Cyclization: An Entry to Functionalized Cycloalkane-Fused Naphthalenes

Functionalized angular cycloalkane-fused naphthalenes were prepared using a two-step process involving a Pd-catalyzed Suzuki-Miyaura coupling of aryl pinacol boronates and vinyl triflates followed by a boron trifluoride etherate-catalyzed cycloaromatization.
