Description and Uses
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.
