Several carbosilane wedges of generations 1–3 have been synthesized, following the divergent method, containing at the focalpoint a C–Br bond and as peripheral functional groups SiMeCl2, SiMe(C3H5)2, SiMe2Cl, SiMe2H, and ester units SiMe2(C3H6)N(C2H4CO2Me)2}. The dendronsfunctionalized with SiMe(C3H5)2 and SiMe2(C3H6)N(C2H4CO2Me)2} groups were used to synthesize spherical dendrimers derived from

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

Highly branched macromolecules synthesized from a polyfunctional core, preferably silicon, or polyphenolic, with a carbosilane structure at its periphery functionalized with groups, preferably anionic, giving to the macromolecule a net negative charge. Furthermore, the invention relates to the procedures for their synthesis and their uses as antiviral agents, antibacterial and antifungal agents.

(hex-5-ynyl)silanes was achieved following two different synthetic approaches from readily available materials such as 4-bromobutene, 6-iodohexyne and chlorosilanes. Different reaction conditions for intramolecularhydrosilylation were tested to prepare the corresponding 2-methylidene-1-silacyclohexanes. Notably, the use of Speier’s catalyst allowed the regioselective formation of the desired products in moderate
