DETAILS

Description (English)
Packaging
10 g in glass bottle
Application
Reactant for:
• Preparation of 1,3-diketones, β-keto esters, and β-keto phosphonates via 1,2-addition of carbanionic nucleophiles to cyclic vinylogous acyl triflates, followed by ring-opening fragmentation, Claisen condensation and carbon-carbon bond cleavage1
• Controlling the surface state emission in ultrasmall CdSe nanocrystals2
• Reactions with organoboranes for synthesis of organophosphorous compounds3
