General Description
Trichloro(tripropylamine)boron is a chemical compound composed of boron, chlorine, and tripropylamine molecules. Structurally, it features a boron atom bound to three chlorine atoms and a tripropylamine ligand. trichloro(tripropylamine)boron finds utility primarily in organic synthesis, where it serves as a Lewis acid catalyst due to the electron-deficient nature of the boron center. The presence of the tripropylamine ligand can influence the reactivity and selectivity of reactions catalyzed by this compound. Trichloro(tripropylamine)boron has been employed in various transformations including C-C bond formation, cyclizations, and functional group manipulations. Its application extends to the synthesis of pharmaceuticals, agrochemicals, and materials science, showcasing its versatility in diverse chemical contexts. Additionally, its relatively low toxicity and compatibility with a range of reaction conditions contribute to its appeal as a catalyst in synthetic chemistry.
Check Digit Verification of cas no
The CAS Registry Mumber 74174-50-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,7 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74174-50:
(7*7)+(6*4)+(5*1)+(4*7)+(3*4)+(2*5)+(1*0)=128
128 % 10 = 8
So 74174-50-8 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.
