Mo‐Catalyzed Synthesis of 3‐Substituted Quinolines From Nitroarenes and Aldehydes

European Journal of Organic Chemistry, EarlyView.
A one‐pot Friedländer synthesis of 3‐substituted quinolines from readily available o‐nitrobenzaldehydes and aldehydes or acetals has been developed under dioxomolybdenum(VI) catalysis. Pinacol acts as a benign reductant, enabling in situ nitroarene reduction and annulation without isolation of o‐aminobenzaldehydes and provides access to diverse ...

Combustion Properties of Timber in Historic Structures: Case Study of the São Pedro de Alcântara Chapel Fire

Fire and Materials, EarlyView.
ABSTRACT Timber plays a fundamental role in the fire performance of historic building components, where ageing and environmental exposure can markedly influence its physical and chemical properties. This study presents an experimental investigation of the fire behaviour of Ocotea sp.
