S-Di-ethyl-amino-S-(3-methyl-benzoyl-imino)-S,S-di-phenyl-sulfonium tetra-fluoro-borate

摘要

The title salt, C 24 H 27 N 2 OS + ·BF 4 ? , was prepared by an alkyl-ation at the amino N atom attached to the sulfur atom of the corresponding sulfodi-imide. The configuration around the sulfur atom is a slightly distorted tetra-hedral geometry with two S—N bonds and two S—C bonds. The lengths of the S—N(di-ethyl-amine) and S=N( m -methyl-benzoyl-imine) bonds are 1.619?(2) and 1.551?(2)??, respectively. The two N—S—N—C(eth-yl) and the N—S—N—C( m -methyl-benzoyl-imine) torsion angles are ?85.43?(3), 58.94?(17) and 62.03?(16)°, respectively. The dihedral angle between the two phenyl rings is 84.03?(14)°. In the crystal, C—H?F hydrogen bonds link the cation and anion, forming a three-dimensional network.
