A novel N-sulfonyl aziridine, N-((2-(trimethylsilyl)ethyl)sulfonyl)-2-methyl-aziridine (SES-MeAz) was synthesized, and its controlled anionic ring-opening polymerization to form poly(SES-MeAz) studied. The desulfonylation of poly(SES-MeAz)s can be achieved under mild conditions, with tetrabutylammonium fluoride (TBAF) polypropylene imine (PPI), although purification the PPI not completely succe...
The title compound, C(23)H(18)N(2)O(4)S(2), contains a pyrrolo group fused onto the plane of an indole ring with phenyl-sulfonyl and p-toluene-sulfonyl groups bonded to the indole and pyrrolo rings. The angles between the mean planes of the pyrrolo-indole ring and the phenyl-sulfonyl and p-toluene-sulfonyl rings are 73.7 (6) and 80.6 (0)°, respectively. The dihedral angle between the mean plane...
Sulfonyl-derived functional groups populate a broad range of useful molecules and materials, and despite a variety of preparative methods being available, processes which introduce the most basic sulfonyl building block, sulfur dioxide, using catalytic methods, are rare. Described herein is a simple reaction system consisting of the sulfur dioxide surrogate DABSO, triethylamine, and a palladium...
In the title compound, C(14)H(12)N(2)O(5)S, the conformation between the N-H group and the ortho-nitro group in the sulfonyl benzene ring is syn and that between the C=O and meta-methyl groups in the benzoyl ring is anti. The mol-ecule is twisted at the S-N bond with a torsion angle of 64.3 (2)°. The dihedral angle between the sulfonyl benzene ring and the -SO(2)-NH-C-O segment is 75.73 (7)° an...
The crystal structure of the title calcium complex, [Ca(C(8)H(11)NO(5)PS)(2)](n), is composed of a polymeric chain, which is formed due to two bridging sulfonyl groups linking Ca(II) ions in a O-S-O-Ca manner. Thus, the coordination environment of the Ca(II) ions is composed of six O atoms belonging to the phosphoryl and sulfonyl groups of two chelate rings and two additional O atoms of two bri...
The stabilities of a series of isolated covalent selenium(II) azides such as [2-[1-(3,5-dimethylphenyl)-2-naphthyl]-4,5-dihydro-4,4-dimethyloxazole]selenium azide (2a), [2-(4,4-dimethyl-2-oxazolinyl)phenyl]selenenyl azide (3a), [o-(2,6-diisopropylphenyl-iminomethinyl)phenyl]selenenyl azide (4a), [o-(R)-(methylbenzyliminomethinyl)phenyl]selenenyl azide (5a) and o-formylphenylselenenyl azide (6a)...
Sulfonylated aromatics are commonplace motifs in drugs and agrochemicals. However, methods for the direct synthesis of sulfonylated non-classical arene bioisosteres, which could improve physicochemical properties drug agrochemical candidates, limited. Here we report a solution to this challenge: one-pot halosulfonylation [1.1.1]propellane, [3.1.1]propellane bicyclo[1.1.0]butanes that proceeds u...
In the title compound, C(26)H(30)N(2)O(4)S·H(2)O, the pyrrolidine and dihydro-pyran rings adopt envelope conformations and they are cis-fused. The sulfonyl group has a distorted tetra-hedral geometry. In the crystal structure, the mol-ecules are linked into a ribbon-like structure along the a axis by O/C-H⋯O hydrogen bonds involving water mol-ecules and C-H⋯π inter-actions involving the sulfony...
