Syntheses are described of a number of 2,6‐difunctionalized dimethylsilylbenzenes, namely, 1‐(HMe 2 Si)‐2,6‐Cl 2 C 6 H 3 ( 13 ), 1‐(HMe 2 Si)‐2,6‐Br 2 C 6 H 3 ( 14 ), 1,2,3‐(HMe 2 Si) 3 C 6 H 3 ( 15 ), 1,2‐(HMe 2 Si) 2 ‐6‐ClC 6 H 3 ( 16 ), 1,2‐(HMe 2 Si) 2 ‐6‐BrC 6 H 3 ( 17 ), 1‐(HMe 2 Si)‐2‐(Ph 2 P)‐6‐BrC 6 H 3 ( 18 ), diphenyl(1,1,3,3‐tetramethyl‐1,3‐dihydrobenzo[c][1,2,5]oxadisilol‐4‐yl)phosphine oxide ( 19 ) and 8‐Brom‐1,1,3,3‐tetramethyl‐2,2,2,2,‐tetracarbonyl‐1,3‐dihydro‐benzo[d][2,1,3]ferra disilol ( 20 ). Compounds 13 – 20 were characterized by multinuclear NMR spectroscopy and in case of 18 – 20 also by single crystal X‐ray diffraction.
