Key Points

To establish a protocol for synthesizing chalcogen-linked organosulfur and organoselenium frameworks without using transition metals.
DBU mediated coupling of heteroaryl thiocyanates and selenocyanates with alkyl halides
Synthesis of organosulfur and organoselenium frameworks
Use of pseudohalides in the reaction
Successfully synthesized various chalcogen-linked heterocycles
Avoided the need for transition metals in the synthesis
Demonstrated efficiency in using alkyl halides and pseudohalides

Implication

This research demonstrates a method to synthesize chalcogen-linked compounds from thiocyanates and selenocyanates, suggesting efficient alternatives for organic synthesis.

Abstract

We report a transition-metal-free protocol of synthesizing of chalcogen-linked organosulfur and organoselenium frameworks, via DBU mediated coupling of heteroaryl thiocyanates and selenocyanates, with alkyl halides and pseudohalides. In this transformation,...
