Self-supported oligomeric Grubbs/Hoveyda-type Ru-carbene complexes for ring-closing metathesis.
On the basis of the release-return metathesis mechanism, self-supported oligomeric Grubbs/Hoveyda-type Ru-carbene complexes have been designed and synthesized as a new type of recoverable catalyst for ring-closing metathesis. The catalytic activities of the self-supported oligomeric Ru-carbene complex in ring-closing metathesis are comparable to those of their homogeneous counterpart as they work homogeneously and are recovered heterogeneously.
