silylation using hydrosilane was developed. This cross-dehydrogenative silylation enables both electron-rich and electron-poor aromatics to afford the desired arylsilanes in unique selectivity. A “para-selectivity” was observed by examination of over 54 examples. This exceptional orientation is quite different from that in Friedel–Crafts C–H silylation or transition-metal-catalyzed dehydrogenative silylation

ortho-Functionalized styryl ethers are obtained in high yields by palladium-catalyzed cross coupling between (1-ethoxy-1-alken-2-yl)boranes and aryl halides. These styryl ethers are converted to benzo-fused heteroaromatic compounds by cyclodehydration.
