Tribenzylammonium dibenzylammonium tetrachlorocuprate

Tri-benzyl-ammonium chloride

Single crystals of the title salt, C21H21NH(+)·Cl(-), were isolated as a side product from the reaction involving [(C6H5CH2)3NH]2[HPO4] and Sn(CH3)3Cl in ethanol. Both the cation and the anion are situated on a threefold rotation axis. The central N atom in the cation has a slightly distorted tetra-hedral environment, with angles ranging from 107.7 to 111.16 (10)°. In the crystal, the tri-benzyl-ammonium cations and chloride anions are linked through N-H⋯Cl and C-H⋯Cl hydrogen bonds, leading to the formation of infinite chains along [001]. The crystal studied was a merohedral twin.

Tribenzylamine C-H activation and intermolecular hydrogen transfer promoted by WCl6

The 1:1 molar reaction of WCl6 with tribenzylamine (tba), in dichloromethane, selectively afforded the iminium salt [(PhCH2)2N═CHPh][WCl6], 1, and the ammonium one [tbaH][WCl6], 2, in equimolar amounts. The products were fully characterized by means of spectroscopic methods, analytical methods, and X-ray diffractometry. Density functional theory calculations were carried out with the aim of comprehending the mechanistic aspects.

Bis(tribenzyl-ammonium) tetra-chloridoaurate(III) chloride

In the title compound, (C(21)H(22)N)(2)[AuCl(4)]Cl, the Au(III) atom adopts a square-planar coordination geometry defined by four chloride ions. In the crystal structure, inter-molecular N-H⋯Cl hydrogen bonds link the organic cations and the uncoordinated chloride ion.
