Abstract

Phosphorus chemical shifts are relative to phosphoric acid and not as stated. In compound ( 5 ) the phosphorus chemical shift of the P2C3 ring was omitted; it is +35.6 p.p.m.Typeset and printed by Black Bear Press Limited,

Reaktionen des [η2-{P-PtBu2}Pt(PPh3)2] und [η2-{P-PtBu2}Pt(dppe)] mit Metallcarbonylen. Bildung von [η2-{(CO)5M · PPtBu2}Pt(PPh3)2] (M = Cr, W) und [η2-{(CO)5Cr · PPtBu2}Pt(dppe)]

“…Insbesondere bleibt der P±P-Bindungsgrad der Ausgangsverbindungen bei der Koordination von P2 an das Cr(CO) 5 Metallcluster mit dem unsubstituierten Liganden P 2 wurden bereits strukturell beschrieben [5]. Nixon et al [6] berichten u È ber die Umsetzung von [Fe(g 5 -P 3 C 2 t Bu 2 )(g 5…”

“…Davon koordiniert ein P-Atom an drei Ru-Atome, das andere ist an zwei C-Atome des 1,3-Diphosphacyclobutan-Ringes und an ein Ru-Atom der Ru 3 -Gruppe gebunden. Der P±P-Abstand in der P 2 -Gruppe ist mit 216,4 pm angegeben [6]. Scherer et al [7] beschreiben die Bildung von [(TaL) 3 …”

1-Triorganylstannyl-1,2,4-triphosphole: A Versatile Starting Material for Phosphorus-Rich Cage Compounds and π-Complexes

“…[4,5] In concurrent, but independent, experiments, the reaction of the mixed alkali metal salts M[3,5-di(tert-butyl)-1,2,4-triphospolyl] (M-2) and M[2,4,5-tri(tert-butyl)-1,3-diphospholyl] (M-3) with transition metal halides was performed and yielded the same hexa-and pentaphosphaferrocene derivatives. [6] Both approaches are based on the work of Becker et al, who prepared the starting material tert-butyl phosphaalkyne (1) for the first time, as well as the mixture of the lithium salts Li[3,5-di(tert-butyl)-1,2,4-triphospholyl] (Li-2) and Li[2,4,5-tri(tert-butyl)-1,3-diphospholyl] (Li-3) (Scheme 1). [7,8] However, both reactions produce mixtures of substances that require separation, and the yields of the desired products are often poor, if they are formed at all.…”

“…A rapid suprafacial [1,5]-sigmatropic shift of the SnPh 3 group in 4 a with DG = 31.5 kJ mol À1 indicates a labile PÀSn bondÐone of the characteristic features of 4 a ± 4 c. Compound 4 a provides access to the polycyclic organophosphorus cage compound C 4 tBu 4 P 5 -SnPh 3 (6) …”

Triphospholes as2e and4e donors: Synthesis and structural characterization of the 1,2,4-triphosphole complexes ?1-trans-[PtCl2(PEt3)(P3C2But2CH(SiMe3)2] and ?1-?1-trans-[PtCl2(PEt3)2}2(?-P3C2But2CH(SiMe3)2]

“…expected for a single bond [typically, 2.171-2.266 Å ] [15,16]. The ring [P(1)P(2)C(1)P(3)C (2)] is planar in (3), while in (1) and (2) only the atoms from the diene system [P(2)C(1)P(3)C (2)] lie in the same plane.…”
