A rearranged acetylene from an E1 solvolysis of a substituted α-trimethylsilylvinyl system

The reaction of Mes2C=C(OH)SiMe2R (R=Me, SiMe3) with SOCl2 gives the rearranged elimination product MesC≡CMes, presumably via β-mesityl participation in the solvolysis of the derived OSOCl derivative, followed by 'Me3Si+' loss from the rearranged ion MesC(Me3Si)=C-Mes. Under the same conditions, the carbon analogue Mes2C=C(OH)Bu-t gives the ketone Mes2CHCOBu-t and benzofurans via non-solvolytic reactions.

Synthesis of diarylalkynes via tandem Sonogashira/decarboxylative reaction of aryl chlorides with propiolic acid

A facile and efficient protocol for one-pot synthesis of diarylalkynes via tandem Sonogashira/decarboxylative coupling has been developed. The remarkable features of this reaction include using commercially available aryl chlorides as starting materials and taking the propiolic acid instead of expensive terminal alkynes as an acetylene source. This journal is the Partner Organisations 2014.
