Near-perfect dipole parallel-alignment in the highly anisotropic crystal structure of 4-iodoacetophenone-(4-methoxyphenylethylidene) hydrazone
Lewis, Michael,Barnes, Charles L.,Glaser, Rainer
, p. 489 - 496 (2000)
The title compound crystallizes in the space group Pna2(1) with cell parameters a = 6.4606(3), b = 7.2155(3) and c = 33.5878(16) A. The azine shows a gauche conformation about the N - N bond and there is an angle of 58.1° between the benzene rings of each azine. This conformation allows for two intermolecular arene-arene T-contacts between pairs of benzene rings. The characteristic structural motif features T-contact formation between like-substituted arene rings and this architecture results in a highly dipole-parallel aligned lattice. All azines are perfectly colinear within each layer and the orientations of the azines in different layers are nearly the same. The surfaces of the layers exhibit a quadrilateral kite-shaped arrangement of I-atoms and of OCH3-substituents. The layers pack such that the OCH3 - carbon atoms are placed above the interstices between the I-atoms in the adjacent layer.
Sequential Cleavage of Lignin Systems by Nitrogen Monoxide and Hydrazine
Altmann, Lisa-Marie,Heinrich, Markus R.,Hofmann, Dagmar,Hofmann, Laura Elena,Prusko, Lea

The cleavage of representative lignin systems has been achieved in a metal-free two-step sequence first employing nitrogen monoxide for oxidation followed by hydrazine for reductive C?O bond scission. In combining nitrogen monoxide and lignin, the newly developed valorization strategy shows the particular feature of starting from two waste materials, and it further exploits the attractive conditions of a Wolff-Kishner reduction for C?O bond cleavage for the first time.
