Various mesityl, alkoxy and aryloxy-stibanes were prepared from the corresponding mesitylchlorostibanes. The reaction of the same mesitylchlorostibanes with the 3,5-di-t-butyl catechol first leads to the formation of a Sb V complex observed by ¹H NMR. Depending on the experimental conditions the reaction can fork from this intermediate. Intramolecular hydrochloride elimination when this is trapped using a tertiary amine, leads to 2-mesityl-1,3-dioxa-4,6-di-t-butylbenzo-2-stibolane while the absence of a tertiary amine allows an acidic cleavage of the mesityl-antimony bond with formation of 2-chloro-1,3-dioxa-4,6-di-t-butylbenzo-2-stibolane.
