Every value is as the source recorded it. A run with no yield was reported without one, and nothing here is averaged, modelled or filled in.

Procedure

Copied from the source record, unedited

pre-ligate Ni(cod)2 and phosphine ligand in dioxane for 15 minutes in a separate plate

How to read this record

This is one experiment, not a rule. It says that on one occasion these species were combined under these conditions and this came out. It does not say the reaction will give the same result on your substrate, and nothing on the page has been generalised into a claim that it would.

The pathway is a separate question, kept on separate pages. A mechanism here is the canonical arrow pushing for a class, run on real structures and labelled rule-derived. It is not evidence, and this record is not a mechanism.
