Silaphenylmercuric Triflate Catalyzed Reactions: Synthesis of a Solid-Supported Mercuric Salt Catalyst


  • We are grateful to Prof. Seiichiro Himeno of this institute for kind advice on determining Hg content. This study was financially supported by a Grant-in-Aid from the Ministry of Education, Culture, Sports, Science, and Technology of the Japanese Government, and MEXT-HITEC.


Let it flow, let it flow: A procedure to generate the first solid-supported mercuric salt, silaphenylmercuric triflate, is described. Silaphenylmercuric triflate showed remarkable catalytic activity for an indole synthesis, furanoyne cyclization, arylyne cyclization, and tandem carbocyclizations. An efficient flow reaction system for indole synthesis and arylyne cyclization is also described (see figure).
