Beiträge zur Chemie des Phosphors. 223. Hexaisopropyl‐icosaphosphan(6), P20i‐Pr6 — Darstellung und kernresonanz‐spektroskopische Strukturbestimmung von zwei Konstitutionsisomeren

Abstract: Hexaisopropylicosaphosphan(6) wurde durch Reaktion von i‐PrPCl2, P4 und Magnesium und anschließende Thermolyse des Rohproduktes gewonnen. Die Verbindung entsteht als Gemisch von zwei Konstitutionsisomeren 1 und 2 gleicher Häufigkeit, von denen 1 als Gemisch der Diastereomere 1 a, 1 b und 2 in Form der getrennten Konfigurationsisomere 2 a und 2 b durch Hochdruckflüssigkeitschromatographie weitgehend rein isoliert werden konnten. Nach kernresonanzspektroskopischen Untersuchungen bestehen die neuen Konjunkto‐Phos… Show more

“…Thus, the reduction of iPrPCl 2 with Mg in the presence of P 4 followed by thermolysis of the reaction mixture leads, depending on the reaction conditions, to the polycyclic phosphanes P 11 iPr 3 , 121 P 11 iPr 5 , 122 P 12 iPr 4 , 123,124 P 13 iPr 5 , 123 P 14 iPr 4 , 125 P 14 iPr 6 , 126 P 18 iPr 6 , 127 and P 20 iPr 6 . 128 Similarly, the reduction of RPCl 2 (R ) Me, Et) with Mg in the presence of P 4 leads, among monocyclic phosphanes, 42 to P 9 R 5 , P 10 R 6 , P 10 R 4 , P 11 R 5 , P 12 R 4 , and P 13 R 5 (R ) Me, Et, CHMe 2 ). 129 The thermolysis of the cyclopentaphosphane (EtP) 5 with P 4 leads to P 7 Et 3 along with P 9 Et 3 .…”

“…The nature and distribution of the products depends considerably on the bulkiness of the organic group and on the reaction conditions. Thus, the reduction of i PrPCl 2 with Mg in the presence of P 4 followed by thermolysis of the reaction mixture leads, depending on the reaction conditions, to the polycyclic phosphanes P 11 i Pr 3 , P 11 i Pr 5 , P 12 i Pr 4 , , P 13 i Pr 5 , P 14 i Pr 4 , P 14 i Pr 6 , P 18 i Pr 6 , and P 20 i Pr 6 . Similarly, the reduction of RPCl 2 (R = Me, Et) with Mg in the presence of P 4 leads, among monocyclic phosphanes, to P 9 R 5 , P 10 R 6 , P 10 R 4 , P 11 R 5 , P 12 R 4 , and P 13 R 5 (R = Me, Et, CHMe 2 ) .…”
