Preparation and spectroscopic characterisation of dithia-arsolium and -stibolium cations: evidence for pπ-pπ bonding of sulphur with arsenic and antimony
Abstract
5-Methyl-1,3,2-benzodithiarsolium and 5-methyl-1,3,2-benzodithiastibolium cations have been prepared and the naphthalenic nature of the compounds is strong is evidence for the presence of unique pπ-pπ bonding of sulphur to arsenic and antimony.
