Coordination chemistry of trivalent and pentavalent organoarsenic heterocyclic dithiocarbamate derivatives: synthesis and characterization

[GRAPHICS] A series of diphenylarsenic(III) and triphenylarsenic(V) derivatives of heterocyclic dithiocarbamates of the type: [GRAPHICS] and [GRAPHICS] [where X = >CH2 (Pipdtc), >CH-CH3 (4-MePipdtc), >O (Morphdtc), >N-CH3 (N-MePzdtc), and >NH (Pzdtc)] [n = 1 or 2] have been synthesized by reactions of diphenylarsenic(III) chloride and triphenylarsenic(V) dibromide with the sodium salt of heterocyclic dithiocarbamates in 1 : 1 and 1 : 2M ratios, respectively, in refluxing benzene. All these newly synthesized compounds have been characterized by their elemental analyses, molecular weight measurements, and ESI mass studies. Structures of the compounds have been proposed on the basis of IR, H-1, and C-13 NMR spectral data which suggest anisobidentate mode of bonding.
