New multiarm stars have been synthesized based on polylithium derivatives of high-generation carbosilane dendrimers. In the synthesis of multiarm stars based on the eighth-generation dendrimer, steric hindrances were observed even during the synthesi

Polydimethylsiloxanes with Si–H bond were coupled with 4-boronated styrene to produce α- and β-regioisomers, whose organoboron moiety was subjected to Suzuki reaction with bromobenzene to afford promising biphenyl-capped polysiloxanes.
