FLUORINE-CONTAINING CYCLOTRISILOXANE

Title:

FLUORINE-CONTAINING CYCLOTRISILOXANE

Document Type and Number:

Japanese Patent JPH0717984

Kind Code:

A

Abstract:

PURPOSE: To provide a novel compound useful as a raw material for silicone oils or elastomers having high heat resistance, good chemical resistance, good weathering resistance and low surface energy.

CONSTITUTION: A compound of formula I (R is 1-6C alkyl), a compound of formula II. The compound of formula I is obtained by oligomerizing a compound of formula: CF3CF=CF2, reacting the produced oligomer of formula: (CF3)2C =CFCF2CF3 with a compound of formula: BrCH2CH=CH2 in the presence of KF in a polar solvent, hydrosilylating the obtained olefin compound in the presence of a platinum catalyst, and subsequently cyclizing the fluorine- containing dichlorosilane compound of formula IV with a disiloxanediol of formula V in the presence of an amine.
