Crystalline dendritic arylalkylsilane/tetrahydrofurane inclusion complexes

Dendrimers Derived from 1 → 3 Branching Motifs

“…The crystal structure of the dendrimer/THF inclusion complex was later reported. 885 These 1 f 3 branched carbosilanes using polyhedral silsesquioxane (POSS) cores have been reported; 886 a singlecrystal X-ray structure was obtained for the 24-vinylterminated dendrimer 334 (Figure 13), revealing disorder in the vinyl moieties. Treatment of the trichlorosilane surface groups with LiCH 2 PR 3 (R ) Me, hexyl, or Ph) gave the desired POSS capped with phosphine moieties; 887 these were shown to catalyze hydroformylation reactions.…”

“…Friedmann et al employed similar technology for the construction of the G1−2, Si-based dendrimers with bulky triphenylsilane termini; the crystal structure of the smaller dendrimer was obtained, and the NMR data supported solvent exchange and the formation of inclusion compounds in higher generations in this series. The crystal structure of the dendrimer/THF inclusion complex was later reported …”
