TRIS(DIBENZYLIDENEACETONE)DIPALLADIUM(0) (0.046 g, 0.05 mmol) and rac-2,2'-bis(diphenylphosphino)-1,1'-binaphthyl (0.063 g, 0.10 mmol) were mixed together and evacuated and purged with nitrogen 3 times. toluene (24.91 ml) was added and the resulting mixture heated to 50°C for 10 minutes. In a second reaction vessel was mixed sodium tert-butoxide (0.387 g, 4.03 mmol), (1S,4S)-tert-butyl 2,5-diazabicyclo[2.2.1]heptane-2-carboxylate (0.500 g, 2.52 mmol), 1-bromo-2-methoxybenzene (0.314 ml, 2.52 mmol) and toluene (24.91 ml). The mixture was evacuated and purged with nitrogen 3 times. The solution of catalyst was added to the reaction mixture and the resulting mixture was heated at 105 °C for 16 hours. The reaction mixture was cooled to RT and filtered through celite and evaporated. The cru

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.
