Linear Carbosilanes

Similarly, linear carbosilanes react to produce their respective SiCl-containing analogues 

ClMe2Si-CH2-SiMe2-CH2-SiMe3 -h Me3Si-CH2-SiMeCl-CH2-SiMe3 

The compound present with the highest degree of chlorination is (ClMe Si--CH2)2SiMeCl [154, 160].

Using our experience in the cyclization of linear carbosilanes having four Si atoms29, we carried out reactions (48a). 

The other procedure described for the generation of multivalent globotriaose dendrimers for protection against VTl or VT2 cytotoxicity in vivo is based on carbosilane multimers (183). These multimers are more systematic expansions of trimeric structures that are based on multiples of the tetrameric carbosilane (184). In these studies, coupling the two terminal silicon residues of a linear carbosilane trimer ( super twig ) to either... 

A prerequisite for building up cyclic carbosilanes with functional groups is the preparation of linear carbosilanes with more than two functional groups distributed in the desired way on different Si atoms. A trisilacyclo-hexane with two Si functional groups has been prepared according to the scheme on page 382 (42).

The C-chlorinated linear carbosilanes are liquids, while (Cl3Si—CCl2)2SiCl2 is a viscous compound which degrades on attempted distillation. 

This corresponds closely to the reaction of one CCI2 group between two Si-atoms in linear carbosilanes such as (Cl3Si)2CCl2. 

CH2)3 or linear carbosilanes do not succumb to this reaction. The bond polarization... 

The products are shown in Table 67. Only linear carbosilanes were detected simple HBr addition to the double bond did not appear. However, such an addition cannot be ruled out as a probable initial reaction step [146].
