Analysis of Halogenated Polycyclic Aromatic Hydrocarbons in the Air

Iodine-Catalyzed Prins Cyclization of Aliphatic and Aromatic Ketones

A ciclização de Prins catalisada por iodo entre álcoois homoalílicos e cetonas foi investigada. Condições anidras e atmosfera inerte não são necessárias neste protocolo ausente de metais. A reação do 2-(3,4-di-hidronaftalen-1-il)propan-1-ol com seis cetonas simétricas alifáticas levou ao produto desejado em 67-77% de rendimento. A ciclização foi realizada com quatro cetonas alifáticas assimétri...

Catalyst development for organocatalytic hydrosilylation of aromatic ketones and ketimines.

A new family of Lewis basic 2-pyridyl oxazolines have been developed, which can act as efficient organocatalysts for the enantioselective reduction of prochiral aromatic ketones and ketimines with trichlorosilane, a readily available and inexpensive reagent. 1-Isoquinolyl oxazoline, derived from mandelic acid, was identified as the most efficient catalyst of the series, capable of delivering hi...

Metal-Free Trifluoromethylation of Aromatic and Heteroaromatic Aldehydes and Ketones

The ability to convert simple and common substrates into fluoroalkyl derivatives under mild conditions remains an important goal for medicinal and agricultural chemists. One representative example of a desirable transformation involves the conversion of aromatic and heteroaromatic ketones and aldehydes into aryl and heteroaryl β,β,β-trifluoroethylarenes and -heteroarenes. The traditional approa...
