What is 1,2-PHENYLENE PHOSPHOROCHLORIDITE?
Chemical properties
Colourless Liquid Which Solidifies at Low Temperature
The Uses of 1,2-PHENYLENE PHOSPHOROCHLORIDITE
Highly reactive cyclic phosphitylating reagent which provides fast coupling rates, and hydrolytic cleavage occurs more readily than with acyclic analogs
The Uses of 1,2-PHENYLENE PHOSPHOROCHLORIDITE
- Catalyst in synthesis of bakkane sesquiterpenes
- Reactant in reversible halogen-halogen ligand substitution at room temperature, and in irreversible halogen-O substitution at higher temperatures
- Reactant in preparation of gold(I) trimethoxybenzonitrile phosphine isolated precatalysts
- Reactant for preparation of pyrroles by TMSOTf-catalyzed Arbuzov reaction
- Phosphorylation agent
- Reactant for reparation of vinyl-substituted spirophosphoranes and vinylphosphonates via Markovnikov addition
