Leather, a textile based on collagen, usually requires the addition of sulfated oils that have been recently found to cause instability when heated in critical manufacturing processes. Here reactions between collagen and sodium dodecyl sulfate (SDS), sulfated castor oil, or a synthetic sulfated oil

Lithium bis(N,N-dimethyl-2-aminoethyl)amide (1 a) and lithium N-methyl-N- (3,6-diaza-3,6-dimethyl)heptylamide (2) are dimers in toluene, THF and in the crystalline state where they exhibit diamond-shaped Li 2 N 2 cores. Tetracoordination of lithium is achieved by intramolecular binding of the amine
Addition of the chiral amine (S)-methyl(1-phenyl-2-pyrrolidinoethyl)-[ 15 N]amine (1) to a large excess of nBuNa resulted in the formation of a mixed sodium amide/nBuNa complex. This is the first observation of such a complex. Addition of nBuLi to the chiral sodium amide dimer 3 gave a new mixed lit
