Acyl‐ und Alkylidenphosphane. XX. Bis (2,2‐dimethylpropionyl) phosphan und Bis (2,2‐dimethylpropionyl)phosphide

Abstract: Bis (2,2‐dimethylpropionyl)phosphan 1 a kann mit guten Ausbeuten sowohl aus 2′,2′‐Dimethylpropionyl‐[2,2‐dimethyl‐1‐(trimethylsiloxy)propyliden]phosphan 1 b und Methanol als auch aus [2,2‐Dimethyl‐1‐(trimethylsiloxy)propyliden]phosphan 2 b und 2,2‐Dimethylpropionylchlorid synthetisiert werden. Nach den Ergebnissen einer Röntgenstrukturanalyse [2] liegt die Verbindung im Kristall als Enol‐Tautomeres E‐1 a vor; in Lösung stellt sich ein von der Dielektrizitätskonstanten des Solvens abhängiges Gleichgewicht zwisc… Show more

“…A similar situation is encountered in β‐diketones, the anions of which are versatile ligands, for example acetylacetonate, acac − [6] . Analogously, several transition, main group metal, yttrium and uranium complexes incorporating the BAP − ligand have been synthesized (Scheme 1b) [4,7–9] . Generally, the coordination occurs in the chelating κ 2 ‐O,O′ mode.…”

“…[5] They exist in solution in a keto-enol equilibrium according to Scheme 1a, whereas in the solid state the enol form is favoured. [3,4] A similar situation is encountered in βdiketones, the anions of which are versatile ligands, for example acetylacetonate, acac À . [6] Analogously, several transition, main group metal, yttrium and uranium complexes incorporating the BAP À ligand have been synthesized (Scheme 1b).…”
