Technical Note:
1."Zipper" catalyst for alkene isomerization over up to 30 double bond positions (Ref. 1). Selective isomerization over one position also possible (Ref. 2, 3). Depending on substrate structure, H/D exchange at accessible allylic positions can be accompanied by is omerization (Ref. 4).
