Paragraph 0077-0078, (2020/09/09)
The invention discloses a preparation method of sulfonyl amidine with 2-Picolylamine and DMF-DMA as amine sources. The method comprises the following steps: reacting sulfonyl chloride with 2-Picolylamine to obtain an intermediate product; and then reacting the intermediate product with DMF-DMA in the presence of a catalyst at a temperature of 60-100 DEG C, then performing cooling to room temperature, extracting the reaction solution with ethyl acetate, performing layering, drying and then concentrating to obtain a target product sulfonyl amidine. According to the method disclosed by the invention, the reaction of secondary sulfonamide and DMF-DMA is realized, and the synthesis path of sulfonyl amidine is expanded. The synthetic reaction is simple in operation, mild in condition and convenient in post-treatment, and the obtained intermediate product and the product are high in purity and yield.

a new and convenient procedure has been developed for the preparation of sulfonamides from sodium sulfinates and amines with (n-C4H9)4NBr as bromine source and m-chloroperbenzoic acid as oxidant. This S-N bond formation reaction proceeds efficiently via sulfonyl bromides under neutral conditions to afford the corresponding sulfonamides in good yields at room temperature.

New palladium(II) complexes ([Pd(1-5)2], 6-10, (1-5 = bidentate pyridyl-sulfonamide ligands)) were obtained from the reaction between Pd(OAc)2 and bidentate pyridyl-sulfonamide ligands. The synthesized compounds were characterized by

CsF-Celite is found to be as an efficient reusable catalyst for sulfonylation and desulfonylation of heteroatoms. Sulfonamides and N-acylsulfonamides deprotect efficiently in the presence of CsF-Celite under solvent free conditions to give the free amines or amides in good to excellent yields.
Synthesis of ruthenium(II) complexes containing tridentate triamine (′NNN′) and bidentate diamine ligands (NN′): As catalysts for transfer hydrogenation of ketones
Guennaz, Salih,Oezdemir, Namk,Dayan, Serkan,Dayan, Osman,Cetinkaya, Bekir
experimental part, p. 4165 - 4173 (2011/10/03)
A series of neutral and cationic Ru(II) complexes (1-10), bearing pyridine-based tridentate (′NNN′), pyridine-based bidentate (NN′), and mixed ′NNN′ + NN′ ligands, were synthesized by starting from [RuCl 2(DMSO)4] and [RuCl2(p-cymene)]2 precursors. Solid-state structures of mixed-ligand complexes 9 and 10 were determined by single-crystal X-ray diffraction. Both complexes are unusual in that NN′ ligands were spontaneously oxidized in air under base-free conditions to give imine-amine bidentate ligands upon replacement of p-cymene by meridional ′NNN′. The complexes 1-10 were screened for transfer hydrogenation (TH) of aryl ketones with 2-propanol. The highest catalytic activity was obtained with the complexes containing tridentate ′NNN′ and 7, which contain nonsulfonated 2-(aminomethyl)pyridine. However, for complexes 6a-c, containing p-cymene (a facial tridentate ligand), a slower reaction rate was observed.
Strong ferromagnetic coupling in linear mixed μ-acetato, μ-hydroxo trinuclear copper(II) complexes with N-sulfonamide derivatives - Synthesis, structure, EPR and magnetic properties

Two new trinuclear copper(II) complexes have been synthesised and structurally characterised: [Cu3(L1)2(CH3COO)2 (OH)2(DMF)2] (1) [HL1 = N-(pyrid-2-ylmethyl)benzenesulfonylamide] and [Cu3(L2)2(CH3COO)2 (OH)2]∞ (2) [HL2 = N-(pyrid-2-ylmethyl)naphthalenesulfonylamide]. In both complexes the central copper ion has a regular square planar geometry. The coordination spheres of the terminal copper atoms are square pyramidal, the apical positions being occupied by a DMF oxygen atom in 1 and by a sulfonamido oxygen of the contiguous trimer in 2, as a consequence the latter can be considered a chain of trinuclear species. For the two compounds the three copper atoms are in a strict linear arrangement and adjacent coppers are connected by a hydroxo bridge and a bidentate syn-syn carboxylato group. The mixed bridging by a hydroxide oxygen atom and a bidentate carboxylato group leads to a noncoplanarity of the adjacent basal coordination planes with a dihedral angle of 54.4(1)° for compound 1 and 58.34(3)° for compound 2, Susceptibility measurements (2-300 K) reveal a strong ferromagnetic coupling, J = 94.0 and 59.1 cm-1, respectively, in the mixed-bridged moiety leading to a quadruplet ground state that is confirmed by the EPR spectra. The ferromagnetic coupling arising from the countercomplementarity of the hydroxo and acetato bridges has been discussed on the basis of DFT calculations on model compounds.
