Synthesis of ynone trifluoroborates toward functionalized pyrazoles
Kirkham, James D.,Edeson, Steven J.,Harrity, Joseph P. A.,Stokes, Stephen
, p. 5354 - 5357,4 (2012/12/12)
The synthesis of a range of novel ynone trifluoroborates has been achieved, in a two-pot process from propargylic alcohols. These alkynes have been subsequently used in the formation of a range of pyrazole trifluoroborate salts via cyclization with hydrazines. The products are generated with high levels of regiocontrol and in excellent yields and represent versatile synthetic intermediates.
Indium-mediated synthesis of heterobiaryls
Font-Sanchis, Enrique,Cespedes-Guirao, F. Javier,Sastre-Santos, Angela,Fernandez-Lazaro, Fernando

The palladium-mediated coupling reaction between triorganoindium reagents and organic electrophiles is extended to the synthesis of heteroaromatic compounds. Both electron-rich and electron-poor heterocycles can act as the organic electrophile or as the organoindium derivative.
