Abstract
The present application provides, among other things, compounds and methods for metathesis reactions. In some embodiments, provided compounds promote highly efficient and highly Z-selective metathesis. In some embodiments, provided compounds and methods are particularly useful for producing allyl alcohols. In some embodiments, provided compounds have the structure of formula I. In some embodiments, provided compounds comprise ruthenium, and a ligand bonded to ruthenium through a sulfur atom.

A compound of formula I:
- wherein:
- M is a metal selected from Group VIII;
- each of R1 and L is independently a neutral ligand;
- r is 1-3;
- each of R4 and R5 is independently bonded to M through an sulfur, oxygen, nitrogen, phosphorus or selenium atom;
- R14 is a carbene;
- R4 and R5 are taken together to form a bidentate ligand, or R4 and R5 are taken together with one or more of R1, L and R14 to form a polydentate ligand;
- two or more of R1, L and R14 are optionally taken together to form a bidentate or polydentate ligand;
- and
- each of R1, R4, R5, L and R14 is independently and optionally linked to a tag or support.
