ON DERIVATISATION REACTIONS OF 2-CHLORO-3-DICHLOROPHOSPHANYL-1.3.2- OXAZAPHOSPHORINANE

Abstract

Derivatisation reactions of 2-chloro-3-dichlorophosphanyl-1.3.2-oxazaphosphorinane lb with protic nucleophiles like HNEt₂, C₂H₅OH, CH₂OH and the Franz-reagent NEt₃3HF forming the substituted N-phosphanylphosphorinanes 2-10 are described. Furthermore the temperature dependence of the ² J _PNP-coupling constant of 2-chloro-3-dichlorophosphanyl-1.3.2-oxazaphosphorinane lb and 2-diethylamino-3-bis(diethylamino)phosphanyl-1.3.2-oxazaphosphorinane 2 in a range from 203 K to 353 K was investigated.

Key Words:

• N-phosphanylphosphorinanes
• 2-chloro-3-dichlorophosphanyl-1.3.2-oxazaphosphorinane
• temperature dependence of ² J _PNP.
