METHOD FOR THE PREPARATION OF AMINOPROPYL OR AMINOALKYL FUNCTIONAL POLYALKYL OR ARYL SILOXANES

摘要

A new method for the preparation of aminopropyl terminated or internal functionalized polyalkyl or aryl siloxanes is described. The method involves readily available commercial starting materials and proceeds under mild conditions in high yield. Purification is facilitated over present commercial procedures and a wider variety of internal functionalized siloxanes may be prepared. The method involves hydrosilation of commercially available alkyl or aryl functional hydrosilicones with allyl amine or other alkenyl or arenyl amine in the presence of platinum(0)divinyltetramethylsiloxane or platinum(0)cyclovinyl complexes.
