84227-47-4 Usage

Purification Methods

Dissolve it in CH2Cl2 or CCl4 (1g in 30mL), wash it with H2O (30mL), brine (30mL), H2O (30 mL) again, dry (MgSO4 or Na2SO4), and evaporate. The residue in CH2Cl2 is chromatographed through Al2O3 (eluting with 10% EtOAc in hexane); evaporate, collect the correct fractions and distil (Kügelrohr) them. Log KNa in dry MeOH at 25o for Na+ complex is 2.08. [White et al. Tetrahedron Lett 26 151 1985, Arnold et al. J Org Chem 53 5652 1988.]

Check Digit Verification of cas no

The CAS Registry Mumber 84227-47-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,2,2 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 84227-47:
(7*8)+(6*4)+(5*2)+(4*2)+(3*7)+(2*4)+(1*7)=134
134 % 10 = 4
So 84227-47-4 is a valid CAS Registry Number.

Synthesis of monoazacrown ethers under phase-transfer catalysis

Luk'yanenko,Basok,Kulygina, E. Yu.,Bogashchenko, T. Yu.,Yakovenko

, p. 1345 - 1352 (2013/02/22)

A procedure has been proposed for the synthesis of monoazacrown ethers by reaction of N-benzyldiethanolamine with oligo(ethylene glycol) bis-p-toluenesulfonates in a two-phase system aromatic hydrocarbon-50% aqueous alkali, followed by removal of the benzyl group by catalytic hydrogenolysis. The maximal yields of N-benzylaza-12-crown-4, -18-crown-6, and -21-crown-7 were achieved by adding 4-10 equiv of LiCl, BaBr2, and CsCl, respectively, to the reaction mixture, which probably indicated template effect.

Cation Binding Properties and Molecular Structure of the Crystalline Complex (Aza-12-crown-2)2*NaI

White, Banita D.,Arnold, Kristin A.,Garrell, Robin L.,Fronczek, Frank R.,Gandour, Richard D.,Gokel, George W.

, p. 1128 - 1133 (2007/10/02)

Aza-12-crown-4 forms a 2:1 sandwich complex similar to that known for 12-crown-4 sodium iodide, except that the presence of >NH in each ring makes Na-donor bonds unequal in strength and leads to hydrogen bonding with the counterion.The heteroatoms of each macroring are coplanar, and both nitrogens are on the same side of the complex (twist angle 43 deg from eclipsed).This may be due to a long (and weak) hydrogen bond to iodide, an interaction confirmed by analysis using Raman spectroscopy.The previously unreported 1:1 and 2:1 cation affinity constants (anhydrous MeOH , 25 deg C) for this macrocycle are logKS(1:1) = 1.3 +/- 0.1 and logKS(2:1) = 2.0 +/- 0.1, respectively.

SYNTHESES AND CATION BINDING PROPERTIES OF 12-MEMBERED RING NITROGEN-PIVOT LARIAT ETHERS

White, Banita D.,Dishong, Dennis M.,Minganti, Carlo,Arnold, Kristin A.,Goli, D.M.,Gokel, George W.

, p. 151 - 154 (2007/10/02)

The efficient synthesis of several 12-membered ring, N-pivot lariat ethers are reported and it is shown that binding to sodium cations is weak except when an oligoethyleneoxy sidearm is long enough to provide additional solvation.
