- DBN hexafluorophosphate salts as convenient sulfonylating and phosphonylating agents
-
Air-stable N-sulfonyl and N-phosphonyl DBN hexafluorophosphate salts have been synthesised under mild conditions as sulfonylating and phosphonylating agents. These salts are highly efficient in the sulfonylation and phosphonylation of a range of N- and O-nucleophiles to generate sulfonamides, sulfonate esters, phosphoramidates and phosphonate esters in good yields.

- Nucleophilic Substitution at the Tetracoordinated Phosphorus Atom. Reactivity of Amines towards Diphenyl Chlorophosphate in Acetonitrile
-
Tertiary alkylamines, pyridines, and imidazoles catalyze the hydrolysis of diphenylchlorophosphate (acetonitrile, 25°C) by a nucleophilic mechanism with the rate-determining attack of an amine on the substrate. Primary and secondary alkyl and arylamines f

- THE REACTIVITY OF MANGANESE DIETHYLAMIDE WITH PHOSPHATE TRIESTERS
-
Manganese bis-(diethylamide) reacts with phosphoric triesters with a selective displacement of single ester function by the diethylamide group.In the reaction of the manganese reagent with dialkyl phosphites products of both, mono- and disubstitution were observed.

- Process for preparing 0,0-diaryl N,N-dialkyl phosphoramidates
-
Flame retardant compounds, O,O-diaryl N,N-dialkyl phosphoramidates are prepared by reacting a phosphoramidohalidate or a phosphoramidic dihalide with a phenol in the presence of an alkali or alkaline earth metal hydroxide and a water-insoluble, water-immiscible, non-hydroxylic polar ketone which is a solvent for both the reactants and the product. High yields are obtained.
