Abstract

Abstract A series of 2, 5-diaryl-3, 4-diphenylsiloles, with various mono-substituted phenyl groups, extended π-conjugated groups, and heteroaryl groups as aryl groups at the 2, 5- positions, has been prepared by a one-pot synthesis from bis (phenylethynyl) silanes based on the intramolecular reductive cyclization followed by the palladium-catalyzed cross- coupling with aryl halides. Crystal structures and chemical reactivities toward the alkaline ...
