, Fukuoka 816-8580, Japan 10.3762/bjoc.16.39 Abstract We have developed a catalytic synthetic method to prepare phenoxasilins. A borane-catalyzed double sila-Friedel–Crafts reaction between amino group-containing diaryl ethers and dihydrosilanes can be used to prepare a variety of phenoxasilin derivatives

Six-membered silacyclic compounds, such as phenoxasilin and phenothiasilin derivatives, are attractive compounds for applications as organic electronic materials [1][2][3][4], ligands [5
-Friedel–Crafts reaction is emerging as a powerful tool for C–H silylation [28][29]. In addition, intra- and intermolecular sila-Friedel–Crafts reactions have been recently developed [30][31][32][33][34][35][36][37][38][39], which have great potential as efficient synthetic strategies to construct
