Chemistry of Phosphorus Ylides, Part 30. Reaction of Camphorquinone Derivatives with Active Phosphacumulenes and Stabilized Phosphonium Ylides

Abstract

THE REACTION of the bifunctional camphorquinone(1) , its monophenylhydrazone (13) and monooxime (16) with the active phosphacumulenes (2) was performed. Phosphanylidene- cyclobutylidenes (5), azitidine bicyclo heptanones (14) and phosphanylidenes (17) were obtained, respectively. On the other hand, the stabilized phosphonium ylides (6) react with the above mentioned substrates (1, 13, and 16) to give the corresponding oxaphosphetane (8), phosphanylidene (10) oxatricycloundecadiene (12), azaphosphetidines (15) and the azatricyclo- undecadienone (19).
