1,2-PHENYLENE PHOSPHOROCHLORIDITE Usage And Synthesis

Chemical Properties

Colourless Liquid Which Solidifies at Low Temperature

Uses

Highly reactive cyclic phosphitylating reagent which provides fast coupling rates, and hydrolytic cleavage occurs more readily than with acyclic analogs

Uses

• 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
