Über das tetratertiäre Phosphin Tetrakis(diphenylphosphinomethyl)‐methan

Abstract: In der letzten Zeit wurde uber die Darstellung von di-, tri-und tetratertiaren Alkyl-und Arylphosphinen (R2P -[CH& -PR2, H3C -C(CH2PR2)3, P(C&PRz)3 ; R = Alkyl oder Aryl, n = 1 -5) und ihr komplexchemisches Verhalten berichtet 1-5). Sie wirken als zwei-, drei-und vierziihnige Liganden und streben allgemein danach, ihre maximale Koordinationsfahigkeit an nur einem Koordinationszentrum (Metallatom oder -ion) zu erreichen. Auf diese Weise entstehen mono-, bi-und tricyclische Ringsysteme, die uber das gemeinsame K… Show more

“…Unchanged carbonyl (2) and benzene are distilled off in a high vacuum and the inhomogeneous dirty-white residue is heated under reflux for 20 min with anhydrous, N2-saturated ethanol. The ethanolic suspension is filtered and the small crystals of colorless residue are washed with a little alcohol and dried in a vacuum.…”

“…112 hr, the deep blue, stable quinodimethane (2) results in approximately 50 % yield; it can be isolated by filtration. We have also obtained compounds (3) to (6) by analogous procedures; these products are also stable [compounds (2) to (6) decompose above 200 "C].…”

“…Die Verbindungen 4 a, b sind schwingungsspektroskopisch von besonderem Interesse, da sie neben den Phosphinliganden 1 a, b, deren Schwingungsspektren bereits eingehend zugeordnet wurden [19,24,25], nur die Banden brückenständiger COGruppen enthalten. Dabei überrascht, daß die …”
