Synthesis of carbosilane dendrimers based on tetrakis(phenylethynyl)silane

Carbosilane dendrimers of first to third generation were synthesized, using alkynylation/hydrosilation cycles with lithium phenylacetylide and dichloromethylsilane as building blocks and tetrakis(phenylethynyl)silane as a core molecule. The analysis of th

METHOD FOR PRODUCING ORGANOSILICON COMPOUND USING HALOSILANE AS RAW MATERIAL

PROBLEM TO BE SOLVED: To provide a novel method for producing an organosilicon compound. SOLUTION: The method for producing an organosilicon compound includes a reaction step (I) of reacting a halosilane represented by formula (a) with a compound containing a hydrocarbon group represented by formula (b) in the presence of an organic base to generate an organosilicon compound represented by formula (c). (In the formula (I), n is an integer of 0-3; each R1 independently represents a hydrogen atom or a C1-20 hydrocarbon group which may contain a heteroatom; X represents a bromo group (-Br) or a chloro group (-Cl); and R2 represents a compound containing a hydrocarbon group.)

Synthesis of some di- and tricyclic silaalkanes

The mono-, di- and spirocyclic silaalkanes 5, 6 and 9/10 are readily prepared from the di- and tetraallylsilanes 4 and 8 respectively by Cp2Zr induced ring forming reactions. The diallylsilole 16 reacts at 0°C and in presence of an excess of Cp2Zr to the tricyclic compound 19 whereas the silaspiro[4.4]nonadienes 21 and 22 are formed at room temperature. High stereoselectivity is observed in all of these Cp2Zr induced cyclization reactions.
