Phosphinimino‐ und Arsinimino‐phosphoniumhalogenide

Abstract

Phosphinimino‐ und Arsinimino‐phosphoniumhalogenide der Formel R3ENER2NER3⊕X⊖ (E = Phosphor oder/und Arsen, R = Aryl und/oder Alkyl, X = Cl oder Br) wurden auf zwei neuen Synthesewegen hergestellt und durch Elementaranalysen, IR‐ und NMR‐Spektren charakterisiert.

Diiminophosphinate des Lithiums, Samariums und Ytterbiums: Moleku¨lstrukturen von Li[Ph2P(NSiMe3)2](THF)2 und [Ph2P(NSiMe3)2]2Sm(μ-I)2Li(THF)2

“…(1) [7,8] wurden nach bekannten Literaturvorschriften synthetisiert. IR-Spektren: Perkin Elmer 180 und Strukturlosung (Direkte Methoden) und Verfeinerung mit SHELXS-86 [18] und SHELX-76 [19].…”

A remarkably stable copper(I) ethylene complex: synthesis, spectroscopy and structure

“…Here, we report a remarkably stable copper(i) ethylene complex 1, which is easily accessible by utilizing a tailor-made sterically demanding and electron-rich iminophosphanamide, first described by Scherer and Schieder more than 30 years ago, 11 as a co-ligand, generated by in situ deprotonation (Scheme 1). 12 The stability of 1 in the solid state and in solution is unprecedented. Colorless crystals of 1 can be dried at 10 23 mbar at ambient temperature without decomposition.…”

Synthesis of Binam‐P Derived C2‐Symmetric bis‐Iminophosphonamide Ligands. Molecular Structure of [(R)‐Binam(Ph2PN(H)tBu)2]

“…Iminophosphonamide anions [R 2 P(NR′) 2 ] – (NPN) are isolobal analogues of phosphinate anions, in which oxygen atoms are replaced by imido‐groups. Synthesis of this NPN‐ligand family is known from the literature and it is based on two main protocols – the Staudinger reaction, of phosphorus(III) compounds with organic azides and the Kirsanov condensation of bromophosphonium bromides with primary amines in the presence of the auxiliary base and subsequent deprotonation (Chart 1).…”
