Lithium tert-butyl[phenyl(2,2,6,6-tetramethylpiperidino)boryl]amide: A versatile reagent

A new synthesis of tmp(PhB)N(tBuNLi) (1, tmp = 2,2,6,6- tetramethylpiperidino) is presented. Compound 1 reacts with many group 13-15 halides, as well as with BH3·THF, to afford, in most cases, compounds of the type tmp(PhB)NtBu-ERn-1 (E = B, Al, Ga, In, Ge, Sn, P, As, Sb, and R = H, Me, Hal). The borane, alane, gallane and indane derivatives have cyclic structures, as shown by X-ray structure determinations, whereas ERn-1 = GeCl3, SnMe3, SnMe 2Cl, SnCl, catecholatophosphanyl, AsCl2 and SbCl 2 are noncyclic, although the arsane and stibane derivatives show weak intramolecular E-N coordination to the tmp-N atom.

Contributions to the Chemistry of Boron, 167. Synthesis of Diazadiboretidines, Borazines, and Octahydrotetrazatetraborocines via Stannazane Cleavage Reactions

Diazadiboretidines 2 are obtained from the diazadistannetidine 1 or 2NC(CH3)3 by Sn-N cleavage with boron halides RBX2 (R = CH3, C2H5, CH(CH3)2, C6H5, Cl, X = Cl, Br).Borazines 15 are formed, however, by Sn-N cleavage of 2NC(CH3)3 (12) with RBX2 (except with (CH3)2HCBCl2) in a 1:1 ratio. (Stannylamino)boranes are NMR detectable intermediates. - The diazadiboretidines 2 2b - d (R = C2H5, CH(CH3)2, C6H5) do not dimerize in contrast to 2a (R = CH3).The equilibrium constant has been determined for the equilibrium 2a 6, the formation of the dimer obeying a second order rate law. 2 (2e) is metastable at -20 deg C.It forms 4 (8) irreversibly at 20 deg C. - 6 crystallizes in the monoclinic system, space group P21/c.The tubshaped molecule possesses alternating single and double BN bonds (BN: 1.516, 1.404 Angstroem).
