Thiol-Ene Synthesis of Cationic Carbosilane Dendrons: a New Family of Synthons

A variety of neutral and cationic carbosilane dendrons containing a wide range of active groups, such as −N3, −OH, −NH2, and −SH, at the focal points were synthesized from carbosilane vinyl dendrons BrG n V m from generations 1–3 by substitution of the bromine atom at the focal point and functionalization of the vinyl groups via thiol-ene click chemistry with HS(CH2)2NMe2·HCl. These dendritic wedges were characterized by NMR, MS, and elemental analysis.
