Abstract
Selective reduction methods for halogenated carbosilanes and carbodisilanes are disclosed. More particularly, high yields of the desired carbosilanes and carbodisilanes are obtained by reduction of their halogenated counterparts using a reducing agent and tetrabutylphosphonium chloride (TBPC) as a catalyst.
Claims11
A method of synthesizing a carbosilane compound having the formula
- SiHaR4-a
- wherein a=1 to 3 and R is a C1 to C12 alkyl group, a C3 to C12 aryl group, fused bicyclic aryl groups, a substituted phenyl group, or a heterocyclic group, comprising:
- reacting a halogenated carbosilane having the formula RbSiHcX4-b-c, wherein b=1 to 3;
- c=0 to 2;
- b+c=1 to 3;
- X=a halogen atom (Cl, Br or I);
- and R is a C1 to C12 alkyl group, a C3 to C12 aryl group, fused bicyclic aryl groups, a substituted phenyl group, or a heterocyclic group, with a reducing agent catalyzed by using tetrabutylphosphoniumchloride (TBPC) as a catalyst.
