ChemInform Abstract: Phosphorus Compounds of Unusual Coordination. Part 23. Mono- and Diphosphatricyclo(3.2.1.02,7)oct-3-enes: Synthesis from 1,3- and 1,4- Dienes and a Stable Phosphaalkyne.
First published: January 12, 1988
Abstract
The title compounds (IV) and (VI) are obtained via Diels-Alder reaction of the phosphaalkyne (II) with the dienes (I) and (V) followed by ene-reaction with a second mol of (II) and subsequent intramolecular (4+2) cycloaddition.
ChemInform Abstract
The title compounds (IV) and (VI) are obtained via Diels-Alder reaction of the phosphaalkyne (II) with the dienes (I) and (V) followed by ene-reaction with a second mol of (II) and subsequent intramolecular (4+2) cycloaddition. The transformation of the dienes (VII) and (IX) to the title compounds (VIII) is also achieved via the last two reaction steps.
