- Synthesis and structural characterization of phenoxarsin-10-yl dithiocarbamates. O(C6H4)2AsS2CN(CH2CH2)2, a compound containing an asymmetric mononuclear biconnective 1,1-dithiolato ligand
-
Phenoxarsin-10-yl dithiocarbamates O(C6H4)2AsS2CX (X = NMe2, NEt2, N(CH2CH)2, N(CH2CH2)2 or N) have been prepared by the reaction between O(C6H4)2AsCl and sodium dithiocarbamates.The compounds were characterized by IR, mass and NMR (1H and 13C) spectroscopy.The molecular structure of O(C6H4)2AsS2CN(CH2CH2)2 was determined using single-crystal X-ray diffraction.The compound is monomeric and contains an asymmetric monometallic biconnective dithiocarbamato unit (As-S(1), 2.277(1), Angstroem; As...S(2), 3.183(3) Angstroem).The double-bond character of the C-N bond (1.318(5) Angstroem) is in agreement with the NMR data.The dihedral angle (155.2 deg) of the phenoxarsine moiety is almost unaffected by substitution of chlorine by the dithiocarbamato ligand. Keywords: Arsenic; Dithiocarbamates; Phenoxarsine; Group 15

- ARSENATION OF DIPHENYL OXIDE WITH ARSENIC TRICHLORIDE
-
The intermediate o-dichloroarsenodiphenyl oxide formed during arsenation of diphenyl oxide with arsenic trichloride undergoes both intramolecular arsenation to give 10-chlorophenoxarsine and subsequent arsenation with a second AsCl3 molecule to give o,o'-bis(dichloroarseno)diphenyl oxide.
