“…s-cis conformation in the ground state, and that they choose the same array for the reactive conformation under thermal conditions [ l ] . Similar conformational behavior of vinyl phosphine oxides was recently implied by the stereochemistry of their cycloadditions to nitrones and nitrile oxides [2,3], and was also corroborated by the crystal structures of three model compounds of this class [4,5]. As revealed in the same 1,3-dipolar cycloaddition studies [2,6,7], vinyl phosphine sulfides and vinyl phosphine selenides follow closely the reactivity pattern 0x = o 2 .…”

“…Die Gegenüberstellung der Stammverbindungen 10 [20,21] Die NMR-Daten der Vinylphosphanchalkogenide sind im Erwartungsbereich der Substanzklasse fast ausnahmslos unauffällig und gestatten eine Beteiligung an der Strukturdiskussion im Hinblick auf die Lage des A und B verbindenden Gleichgewichts nicht.
