Synthese, Struktur und Metallierung von 1,3,5-Tris(dimethylamino)benzol / Synthesis, Structure, and Metalation of 1,3,5-Tris(dimethylamino)benzene

Abstract

The synthesis of 1,3,5-tris(dimethylamino)benzene (5, Ar–H) is reported. The X-ray structure of 5 reveals two independent molecules in the unit cell both containing planar arene rings; the puckering of the amino substituents is demonstrated to be a consequence of steric interactions. 5 is metalated by n-butyl-lithium to give the isolable aryl-lithium compound Ar–Li (6) from which the phosphane Ar–PCl2 (7) and silane Ar–SiCl3 (8) are obtained.
