The equation does not balance as written. That is usual for an experimental record: the source listed what it put in and what it measured, not a stoichiometric equation.

Conditions

Temperature
50 °C

Only the dimensions the source stated are listed. Anything absent here was not recorded, and it is not inferred from what the class usually needs.

Yield

  • 0% of [3-(Trifluoromethyl)phenyl](3-methoxyphenyl)amine.

Procedure

Copied from the source record, unedited

PdOAc2 (8 mg, 0.04 mmol) and (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (40 mg, 0.07 mmol) were added to a dried vial. The vial was caped with a septa-cap and inerted with nitrogen. Degassed anisole (2 mL)was added and the catalyst mixture was heated to 50ºC for 30 minutes, then cooled down to rt. A dry 2ml microwave vial was charged with sodium 2-methylpropan-2-olate (52 mg, 0.54 mmol). It was caped and inerted with nitrogen. A degassed mixture of 1-bromo-3-(trifluoromethyl)benzene (50 µL, 0.36 mmol) and 3-methoxyaniline (50 µL, 0.45 mmol) in anisole (2 mL) wad added at rt. The catalyst solution was added to the reaction mixture. The nitrogen inlet was removed and the vial was inserted into an alumina block at 100°C. The reaction was stirred over night. After 19h, the rea

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.
