General Description

Tris(dimethylamino)borane is an organoborane generally used as a macrolactamization reagent. It can also be used to prepare tris(alkylamino)borane analogs by transamination of primary and secondary amines.

Check Digit Verification of cas no

The CAS Registry Mumber 4375-83-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,7 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4375-83:
(6*4)+(5*3)+(4*7)+(3*5)+(2*8)+(1*3)=101
101 % 10 = 1
So 4375-83-1 is a valid CAS Registry Number.

BEITRAEGE ZUR CHEMIE DES BORS. CLXXII. DARSTELLUNG, STRUKTUR UND REAKTIONEN VON μ-(BORANDITHIOLATO)BIS(TRICARBONYLEISEN)-VERBINDUNGEN, XBS22

Noeth, Heinrich,Rattay, Wilfried

, p. 131 - 152 (1986)

Li2S2Fe2(CO)6 and M2S2Fe2(CO)6nBEt3 (M=Li, Na) have been used to prepare a wide range of the compounds XBS2Fe2(CO)6 (X=NR2, R, Hal) as well as the μ-(bis(dimethylamino)diborane(4)di-thiolato) derivative (4).Reaction of Li2S2Fe2(CO)6 with 2-chloro-1,3-dimethyl-1,3,2-diazaborolidine yields a spirocyclic product.The Me2N group in the Me2NBS2Fe2(CO)6 can be readily exchanged for chlorine or bromine using the respective boron halides as electrophilic reagents.Similarly, 4 can be transformed into the dimethylamino-chloro or -bromo derivatives.Further substitution, using BCl3 and Me2N(Cl)B2S2Fe2(CO)6 leads to Cl2B2S2Fe2(CO)6, which can be de tected by 11B NMR at low temperature, but the compound decomposes at ambient temperature to produce ClBS2Fe2(CO)6.Nucleophilic displacement of Cl- for OtBu- or R- is readily achieved by treating ClBS2Fe2(CO)6 with KOtBu or LiBu.Attack at the B-S bond has not been observed.The electron density at the iron atoms is only influenced marginally by the various boron substituents as shown by ν(CO); therefore electronic effects are not transduced via the sulfur atoms to the metal atoms.The X-ray structures, which have been determined for tmpBS2Fe2(CO)6 (3), (Me2NB)2S2Fe2(CO)6 (4) and 2S2Fe2(CO)6 (6b) show only slight variations in the S2Fe2 units; a larger S...S separation results in 4 due to the bridging diborane(4) unit.

Alkoxide activation of aminoboranes towards selective amination

Sole, Cristina,Fernandez, Elena

supporting information, p. 11351 - 11355 (2013/11/06)

Piece of the (inter)action: The interaction of alkoxides with the sp 2 Bpin (pin=pinacol) moiety in aminoboranes forms the in situ Lewis acid-base adduct [RO-→B(OR)2-N(R′)2] which enables the amino moiety to react as a strong nucleophile with several electrophiles, thus providing amino alcohols, β-enamino esters, and β-hydroxy amides in a direct and remarkably selective way (see scheme).

Metal Hydroborates and Hydroborato Metalates, 21. Solvates of Lithium (Dimethylamino)trihydroborate

Noeth, Heinrich,Thomas, Steffen,Schmidt, Martin

, p. 451 - 458 (2007/10/03)

Li(Me2NBH3) (1) was prepared by deprotonation of Me2NH*BH3 with LiBu and its solubility determined in various solvents.Compound 1 is unstable in most etheral solvents and decomposes in a reversible reaction into LiH and Li(Me2N-BH2-NMe2-BH3) (2).Five solvates of 1 were characterised by X-ray structure analysis.Li(Me2NBH3)*TMEDA is a dimer in the solid state, and two units are connected to one another by B-H...Li bonds.The crystal structure of Li(Me2NBH3)*0.5 dioxane is represented by layers consisting of tetrameric Li(Me2NBH3) units connected via dioxane molecules.Each Li atom is coordinated to one oxygen atom, one nitrogen atom, and two hydrogen atoms.Also Li(Me2NBH3)*0.5 O2C3H6 forms an extended layer, however with pentacoordinated Li atoms which bear one oxygen, one nitrogen, and three hydrogen atoms.A similar layer structure was also found for Li(Me2NBH3)*O3C3H6 where each Li atom is bound to two oxygen atoms of different trioxane molecules, one nitrogen atom, and two hydrogen atoms.Finally, Li(Me2NBH3)*12-crown-4 retains its molecular integrity in the solid state.Its Li atom is pentacoordinated by four oxygen atoms and one nitrogen atom. - Keywords: Borate lithium (dimethylamino)trihydrido- / TMEDA complex / Dioxane complex / 12-Crown-4 complex

Contribution to the Chemistry of Boron, 224 Reactions and Structure of Electron-Precise Triborane(5) and Tetraborane(6) Derivatives

Linti, Gerald,Loderer, Dirk,Noeth, Heinrich,Polborn, Kurt,Rattay, Wilfried

, p. 1909 - 1922 (2007/10/02)

An improved synthesis of B3(NMe2)5 (2), B4(NMe2)6 (1), and B6(NMe2)8 (4) is reported.From each compound two of the four terminal dimethylamino groups are readily replaced by halogen atoms yielding α,ω-dihalides Bn(NMe2)nX2 (n = 3, 4; X = Cl, Br, I).These are used in turn to replace the substituent X by groups like RO, RS, RHN, R2P, and R.Crystal structure determinations on several of these compounds reveal as a common feature planar (C2N)BB2 and (C2N)B(B)X groups which are arranged in an approximately orthogonal manner to one another with NBBN dihedral angles ranging from 69 to 104.6 deg.Consequently, there is no significant ? bonding between the boron atoms. - Key Words: Triboranes(5), 1,ω-disubstituted / Tetraboranes(6), 1,ω-disubstituted / Hexaborane(8), octakis(dimethylamino)- / Electron-precise polyboranes
