DETAILS

Description (English)
Packaging
5, 25 g in glass bottle
Application
Reagent for the conversion of aldehydes to 1,3-dienes in the presence of Cp2Zr(H)CI.1 Polymerization catalyzed by tantalum pentachloride/triphenylbismuth2 yields polymers with high oxygen permeability.3
Used in a synthesis of highly substituted indenes via palladium-catalyzed carboannulation. Synthesis of indenones via a rhodium-catalyzed reaction with 2-bromophenylboronic acids.
