N,N-dimethylaniline*BF3, also known as N,N-dimethylanilinium tetrafluoroborate, is a chemical compound that consists of an N,N-dimethylaniline cation and a tetrafluoroborate anion. N,N-dimethylaniline is an organic compound derived from aniline, with two methyl groups attached to the nitrogen atom, enhancing its solubility and stability. The tetrafluoroborate anion (BF4-) is a stable, non-coordinating anion, which makes the compound useful in various applications, such as in organic synthesis and as a catalyst in certain reactions. The combination of these two components results in a salt that is often used in the preparation of other organic compounds and as a reagent in chemical reactions due to its unique properties.

455-28-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 455-28-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,5 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 455-28:
(5*4)+(4*5)+(3*5)+(2*2)+(1*8)=67
67 % 10 = 7
So 455-28-7 is a valid CAS Registry Number.

Mixed Boron Trihalide Adducts of Amines: A Multinuclear Nuclear Magnetic Resonance Study

Fox, Arnold,Hartman, Stephen J.,Humphries, Robyn E.

, p. 1275 - 1284 (2007/10/02)

The (19)F chemical shifts of mixed boron trihalide adducts of tertiary amines have a marked dependence on the steric effects of amine substituents, as estimated from the 'cone angle' of the amines.Base strength of the amine has little effect on adduct (19)F shifts, but does have a pronounced effect on the rate of halogen redistribution.The (11)B and (13)Cchemical shifts and (11)B-(19)F coupling constants of the adducts are discussed.Amines NRR'R'' become chiral when complexed to Lewis acids, since complexation stops the rapid inversion process.Because of this the fluorines in R''R'RN*BF2X (X=Cl, Br, or I) adducts are diastereotopic and magnetically non-equivalent, differing in chemical shift by up to 2 p.p.m.The four-adduct system of benzyl(ethyl)methylamine with BF(n)I(3-n)(n=0-3) gives rise to the cation B(PhCH2NMeEt)2F2(1+) which, because of the chirality of the co-ordinated amines, exists in meso and optically active forms distinguishable by (19)F n.m.r. spectroscopy.
