Description

Application

Malonyl chloride can be used as a reactant for the synthesis of:

• Alkaloids with tetracyclic cores such as cyclopiamide A and speradine E.
• 6-tetrathiafulvalene(TTF)-polymer by condensation polymerization with TTF-based dihydroxy monomer.
• N-doped TiO₂ films by molecular layer deposition.
• Alkyne-substituted 1,3-oxazines by reaction with arylpropynamides.

It can also be used as a coupling agent in the synthesis of block copolymers by anionic polymerization.
