The authors regret having incorrectly labelled the molar concentration of 1stGrubbs’catalyst in Fig.3B.

The original manuscript illustrates molar concentration of 1stGrubbs’catalyst at 6 mol/L.This should have been 10 mmol/L;consistent with the molar concentration described in Supporting Information.

We confirm that the correction made in this erratum do not affect the original conclusions.

We have included in this document revised version of the aforementioned figure with correct molar concentration of 1stGrubbs’catalyst at 10 mmol/L.

The authors would like to apologise for any inconvenience caused.
