Synthesis of Benzosiloles by Intramolecular anti-Hydroarylation via ortho-C–H Activation of Aryloxyethynyl Silanes
摘要:
Straightforward synthesis of benzosiloles was achieved by the invention of Pd/acid-catalyzed intramolecular anti-hydroarylation of aryloxyethynyl(aryl)-silanes via ortho-C-H bond activation. The aryloxy group bound to the ethynyl carbon is the key factor for this transformation.

The reactivity of anionic penta-coordinated silicon complexes [RSi(O2C6H4-o)2]−Na+ 1 with nucleophilic reagents has been studied. 1 can be reduced to organosilanes RSiH3 by metallic hydrides. Reactions with an excess of Grignard or organolithium reagents (R′MgX or R′Li) gave tetraorganosilanes RSiR′3. When only two molar equivalents of Grignard reagents (R′MgX) or lithium reagents (R′Li) are added
