Abstract

Abstract A one-pot procedure is described which allows the facile introduction of one or two methylchalcogeno groups into a variety of monobromo or dibromo aromatics. The bromo compounds were converted to their corresponding lithio derivatives by treatment with t- butyllithium in tetrahydrofuran at− 78 C, and these derivatives were then treated, at ambient temperature with elemental sulfur, selenium, or tellurium. The resulting lithium thiolates, ...
