Polycyclic High Density Cage Compounds via Cross Metathesis

Abstract

Synthesis of various highly functionalized caged systems suitable for high energy density materials was accomplished by utilization olefin cross metathesis strategy. Here we observed 100% E selectivity during cross-metathesis by using Grubbs II and N-tolyl Grubbs catalyst. The stereochemistry of olefin formed by cross-metathesis has been determined unambiguously by single-crystal X-ray diffraction study.
