salts of the cation [Mn(NBut)3(NH2But)]+, with Li(NHBut) under selected conditions gave the paramagnetic manganese(VI) analogues of the manganate(VI) anion, [LiL]2[Mn(NBut)4][L = 1,2-dimethoxyethane (dme) or N,N,N′,N′-tetramethylethylenediamine (tmen)], and with HCl gave Mn(NBut)2(NHBut)Cl2, the reaction being reversed by addition of pyridine. Unstable compounds, e.g Mn(NBut)3(C6F5) and Mn(NBut)3(NHBut)

The easy preparation of N-alkyl N-trimethylsilyl alkoxymethylamines is described; these new reagents are very convenient to lead to unsymmetrical secondary amines from organometallic compounds.
The 15N–29Si spin–spincouplingconstants in silylamines have been measured from 29Si satellites in their natural abundance 15N n.m.r. spectra in an INEPT sequence for accumulation of signals and interpreted in terms of Fermi-contact interaction; the sensitivity of 1J(15N–29Si) to dπ–pπ bonding was noted.
N,N′-Dibenzosuberyl-1,1′-Binaphthyl-2,2′-diamine: A Highly Effective Supporting Ligand for the Enantioselective Cyclization of Aminoalkenes Catalyzed by Chelating Diamide Complexes of La(III) and Y(III)

Enantioselective hydroamination/cyclization of representative aminoalkenes catalyzed by chelating diamide complexes of La(III) and Y(III) are described. It is noteworthy that the La(III) complex derived from the sterically demanding ( R )- N , N ′-dibenzosuberyl-1,1′-binaphthyl-2,2′-diamine proligand provides enantioselectivities that are in many cases significantly higher than those obtained with
