Synthesis of Isoquinolylselenocyanates and Quinolylselenocyanates via Electrophilic Selenocyanogen Cyclization Induced by Pseudohalogen (SeCN)2 Generated in situ

A strategy for the synthesis of isoquinolylselenocyanates and quinolylselenocyanates through electrophilic selenocyanogen cyclization has been developed. The feature of this reaction is that the sequential process was induced directly by generated in situ pseudohalogen (SeCN)2 generated in situ. Additionally, the obtained selenocyanates allowed functional group diversification, which could be potential intermediates for valuable compounds.
