Titanocene-Catalyzed Multicomponent Coupling Approach to Diarylethynyl Methanes
摘要:
A titanocene-catalyzed multicomponent coupling to provide diarylethynyl methanes is described. By combining the multifunctionality of Cp2TiCl2 with the traceless dielectrophilicity of aryl aldehydes, all-carbon tertiary centers are obtained in 55-99% yield.
