Zinkorganische Phosphaniminato‐Komplexe mit Heterocuban‐Struktur

Abstract

The organo-zinc heterocubanes [ZnR(NPMe3)I4 with R = CH, scopy, and by crystal-structure determinations. 1 and 2 possess (1) and n-C4Hg (2) were prepared by the reaction of heterocubane structures in which the zinc atoms are linked [ZnBr(NPMe,)

(EtZn)4Zn2(PSitBu3)4 – a Homometallic Phosphanediide of Zinc with a Novel Zn6P4 Cage

“…During this zincation the colorless solution turns yellow. (EtZn) 4 Zn 2 (PSitBu 3 ) 4 (1), which crystallizes from a toluene solution as yellow plates, is thermally stable up to 220 • C, however, it is sensitive towards moisture and has to be handled in an inert gas atmosphere.The molecular structure of the inner core of 1 is represented in Fig. 1.…”

“…Nevertheless, there are reports on bis(alkylzinc) alkylimides as polymerization catalysts [1], however, these compounds are poorly characterized and more recent attempts to prepare (RZn) 2 NR' via zincation of primary alkylamines failed [2]. However, compounds of the type (MeZnNPR' 3 ) 4 with a central Zn 4 N 4 heterocubane cage have been known for more than 35 years [3]. More recent investigations focussed on derivatisation and reactivity of such cage compounds [4].…”

“…The reaction of P(SiMe 3 ) 3 with zinc(II) chloride in the presence of triisopropylphosphane gives Zn 10 Cl 12 (PSiMe 3 ) 4 and volatile chlorotrimethylsilane [5]. The central Zn 6 P 4 heteroadamantane cage is embedded in a zinc(II) chloride matrix.…”
