With aluminum isopropoxide forms a self-supported heterogeneous catalyst for the stereoselective polymerization of phenylacetylene to cis-poly(phenylacetylene).

Check Digit Verification of cas no

The CAS Registry Mumber 120967-70-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,9,6 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 120967-70:
(8*1)+(7*2)+(6*0)+(5*9)+(4*6)+(3*7)+(2*7)+(1*0)=126
126 % 10 = 6
So 120967-70-6 is a valid CAS Registry Number.

Synthesis and properties of some new (η6-arene)cobalt complexes

B?nnemann, Helmut,Goddard, Richard,Grub, Joachim,Mynott, Richard,Raabe, Eleonore,Wendel, Stefan

, p. 1941 - 1958 (2008/10/08)

The preparation of several new types of (η6-arene)cobalt complexes is described. (η3-Cyclooctenyl)(η2,η 2-cyclooctadiene)cobalt (1) reacts with H2 in the presence of arenes and N bases such as piperidine to form (η6-arene)(η1,η 2-cyclooctenyl)cobalt complexes (2). The structure of the 1-η1,4,5-η2-cyclooctenyl ligand was determined by 2D NMR techniques. Complexes 2 react with HBF4·Et2O in the presence of dienes to give (η6-arene)(diene)cobalt tetrafluoroborates (5, 6, 8, 10), which in turn react with NaBEt3H to afford (η6-arene)(η3-allyl)cobalt complexes. When the latter are treated with HBF4·Et2O in the presence of dienes, then (η6-arene)(diene)cobalt tetrafluoroborates are re-formed. (η6-Arene)(butadiene)cobalt tetrafluoroborates can be prepared by treating (5-methylheptadienyl)(η4-butadiene)cobalt with HBF4·Et2O in the presence of arenes. The reaction of 1 with HBF4·Et2O and arene results in the synthesis of (η6-arene)(η1,η 3-cyclooctenediyl)cobalt(III) tetrafluoroborate complexes (18). The NMR evidence for this structure is discussed. The arene ligand in 18 is easily displaced by acetonitrile to give (η1,η3-cyclooctenediyl)tris(acetonitrile)cobalt tetrafluoroborate (21), which is a versatile compound for the synthesis of neutral cobalt complexes with η1,η3-cyclooctenediyl ligands. The crystal structures of (η5-cyclopentadienyl)(η1,η 3-cyclooctenediyl)cobalt (22) and (acetylacetonato)(η1,η3-cyclooctenediyl)cobalt (23) were confirmed by X-ray diffraction techniques. Crystals of 22 are tetragonal, space group P4, with a = b = 16.583 (2) A?, c = 7.995 (1) A?, and Z = 8; R = 0.031 for 2525 unique observed reflections. Crystals of 23 are triclinic, space group P1, with a = 8.4165 (8) A?, b = 8.9539 (9) A?, c = 9.3770 (5) A?, α = 72.588 (5)°, β = 72.224 (5)°, γ = 70.521 (8)°, and Z = 2; R = 0.033 for 3160 unique observed reflections. Both complexes are monomeric and contain similar C8H12Co fragments.
