Vibrational spectroscopic studies of cocrystals and salts. 4. cocrystal products formed by benzylamine, α-methylbenzylamine, and their chloride salts

The chloride salts formed by benzylamine and α-methylbenzylamine have been characterized using X-ray powder diffraction, differential scanning calorimetry, and infrared absorption spectroscopy. In addition, X-ray powder diffraction and differential scanning calorimetry have been used to establish formation or lack of formation of the 1:1 stoichiometric salt-cocrystal products containing the chloride salts and their respective free bases. For α-methylbenzylamine (which contains a single dissymmetric center), the chiral identities of the free bases and chloride salts were found to play a determining role as to whether a salt-cocrystal product could or could not be formed. It was found that a salt-cocrystal product could only be formed if the salt and free base were of opposite absolute configurations. For those systems where the existence of cocrystals was demonstrated, assignments were derived for the observed peaks in the infrared absorption spectra of the reactants and their products.

A new strategy to effectively lock the conformation of substituents at the 3,3′-positions of axial-chiral biisoquinoline N,N’-dioxides was developed based on the strong dipole–dipole interaction between 1,2,3-triazole and pyridine N-oxide rings. The crystal structure and the DFT calculations of 3,3′-bis(1-benzyl-1H-1,2,3-triazole-4-yl)-1,1′-biisoquinoline N,N’-dioxide (3a) provided strong support for this strategy. Furthermore, we successfully demonstrated that readily available 4-trimethylsilyl-1,2,3-triazoles are viable nucleophiles for Hiyama cross-coupling.
The fate of the tert-butylsulfinyl auxiliary after acid-promoted cleavage-a method for recycling t-BuSONH2

Ellman's chiral auxiliary is converted into tert-butylsulfinyl chloride on sulfinamide deprotection with HCl and can be recovered in high yield upon treatment with ammonia. The enantiopure auxiliary can be obtained by trapping the sulfinyl chloride with a chiral alcohol followed by treatment of the resulting sulfinate ester with LiNH2.

Chiral Pb(Sn)-I hybrid organic–inorganic perovskites exhibit outstanding chiral-induced spin selectivity (CISS) performance, but the nontoxic lead-free hybrid materials with high stability are still greatly desired for spin filtering in spintronic applica
