Stabilisierung von (Halogenacetyl)organylphenylphosphanen. Kristallstruktur von Br(OC)4Mn[PMePhC(O)CCl3]

Abstract: Die sehr reaktiven Brom-und Chloracetylorganylphenylphosphane X'X2X3CC(0)PRPh (lax-dx, lay, by) lassen sich mit BrMn(CO)5 (2) unter Bildung der Komplexe Br-(OC)4Mn[PRPhc(0)CX'X2X3] (3ax-dx, 3ay, by) stabilisieren und auf diese Weise durch ihre Massen-, IR-und NMR-Spektren charakterisieren. Nach einer Rontgenstrukturanalyse kristallisiert 3dx in der monoklinen Raumgruppe P24n mit 2 = 4. In den IR-Spektren von 3ax-cx und 3ay, by treten mehr als die vier erwarteten CEO-Absorptionen auf, die auf das Vorliegen von … Show more

“…Similarly, pyrolysis of dimetallated (46) (Equation (16)) deposited a material which when warmed to room temperature afforded poly(p-xylylene) in 40% yield. 71 The heterocycle (48) eliminates ethene or propene at temperatures of 0-40 °C and gives dimer (49) (Equation (18)). The stability of (48) follows the order (R 1 = Me, R 2 = H) < (R 1 = R 2 = H) < (R 1 = H, R 2 = Me).…”
