TRICYCLISCHE PHOSPHORANE AUS KETIMINEN DES 2-TRIFLUORACETYLPHENOLS

Abstract

Phenylphosphonous dichloride and ethyldichlorophosphite reacted with the N-methylimino and iminoderivative of 2-trifluoracetylphenol, 2 and 5, to furnish the tricyclic phosphoranes 3 and 6, whereas the respective N-isopropylimine 7 yielded phosphite 8 unexpectedly, which added hexafluoracetone with formation of the 1,3,2λ⁵σ⁵-dioxaphospholane 9.
