Five-membered arsenic-sulfur-nitrogen heterocycles, RAs(S2N2) (R = Me, Et, (i)Pr, (t)Bu, Ph, Mes).
A series of 5-alkyl/aryl-1,3lambda(4)delta(2),2,4,5-dithiadiazarsoles RAs(S(2)N(2)) (R = Me, Et, (i)Pr, (t)Bu, Ph, Mes) were prepared by a ligand exchange between [(n)Bu(2)Sn(S(2)N(2))](2) and the corresponding organodihalogenoarsines RAsX(2) (X = Cl, I). All products were characterized by NMR, IR, and Raman spectroscopies and mass spectrometry. The crystal structures of the aryldithiadiazarsoles (R = Ph, Mes) were determined.
