Polymerization of aliphatic alkynes with heterogeneous Mo catalysts supported on mesoporous molecular sieves.

Abstract

The application of new heterogeneous catalysts for polymerization of aliphatic alkynes: MoO3 supported on MCM-41, MCM-48, and SBA-15 and Schrock type carbene Mo(1/4CHCMe2Ph)(1/4N-2,6-i-Pr2C6H3)[OCMe(CF3)2]2 grafted on MCM-41 and SBA-15 are reported.
