TL;DR: In this paper, four hydrazone ligands: 2-benzoylpyridine benzoyl hydrone (HBPB), di-2-pyridyl ketone nicotinoyl hydrazon (HDKN), quinoline 2-carbaldehyde benzoyal hydrazones (HQCB), and Quinoline-2 carbaldehyde nicotinyl hydrazons (HQCN) with vanadyl salts have been synthesized and characterized.

TL;DR: A series of new organic nonlinear optical nitrophenylhydrazone crystals based on pyrrole with various substituents (X: -H, -CH3, -CF3) has been synthesized and their polymorphs have been investigated as discussed by the authors.
Abstract: A series of new organic nonlinear optical nitrophenylhydrazone crystals based on pyrrole with various substituents (X: -H, -CH3, -CF3) on the hydrazone group (–CX═N–NH–) has been synthesized and their polymorphs have been investigated. The chromophore 2-((2-(4-nitrophenyl)hydrazono)methyl)-1H-pyrrole (HNPH) exhibits two polymorphs with large macroscopic nonlinearity, with a powder second harmonic generation activity of 420 times and 210 times that of urea at 1.9 μm for the anisotropic polar HNPH-I with Pn space group and the isotropic nonpolar HNPH-II polymorph with P212121 space group, respectively. The microscopic and macroscopic nonlinearities in the crystallographic system have been analyzed theoretically using finite field calculations.

TL;DR: A comparative study on the allylation of a benzoyl hydrazone with allyl trichlorosilane using monosulfoxides, methylene-bridged C2-symmetric bissulfoxide, and ethylene-bridges C2 -symmetrical biss sulfuroxides shows that the enantioselectivity of the process is highly dependent on the spacer between the two sulfinyl sulfurs and the concentration of the reaction.
