The sulfonamide moiety is present among a variety of biologically significant compounds. A facile synthesis is necessary to produce a variety of sulfonamides with the potential to improve human health. Herein, we report a facile methodology for the synthesis of 4-methylbenzenesulfonamides, amenable to a broad range of nitrogen nucleophiles. Implementing a semi-miscible biphasic solvent system resulted in higher yields, decreased reaction times, and a simplified workup over preliminary methods. Additionally, the crystal structures of five novel sulfonamide compounds and two polymorphs, have been determined by X-ray diffraction. Results obtained through spectroscopic characterization support the successful formation of the desired 4-methylbenzenesulfonamides.

Abstract The reaction of Y(NO3)3 · 5H2O and 2,2':6',2"-terpyridine (terpy) in MeCN leads to [Y(N03 )3(terpy)(H2O )] (1) and [Y(N03 )3(terpy)(H2O )] terpy-3MeCN (2) in good yields depending on the isolation conditions. The structures of both complexes were determined by single-crystal X-ray crystallography. The YIII atom in 1 is 9-coordinate and ligation is provided by one terdentate terpy molecule, two chelating nitrates, one monodentate nitrate and one terminal H2O molecule; the coordination polyhedron about the metal may be viewed as a tricapped trigonal prism. The YIII atom in 2 is 10-coordinate and its coordination sphere consists of three nitrogen atoms from the terdentate terpy, six oxygen atoms from the three chelating nitrates (one of them being “anisobidentate”) and one oxygen atom from a terminal H2O molecule; the polyhedron about the metal may be viewed as a distorted sphenocorona. The interstitial terpy is strongly hydrogen-bonded to the O atom of the coordinated H2O molecule to form [Y(NO3 )3(terpy)(H20)] ··· terpy pairs. The new complexes were characterized by IR and 1H NMR spectroscopies. The YIII/NO3-/terpy chemistry is compared to the already well-developed LnIII/NO3-/terpy chemistry (Ln = lanthanide).
