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
100 °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 Methyl 3-anilino-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoate.

Procedure

Copied from the source record, unedited

aniline (0.360 mL, 3.95 mmol) was added to methyl 3-chloro-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoate (900 mg, 3.03 mmol), TRIS(DIBENZYLIDENEACETONE)DIPALLADIUM(0) (139 mg, 0.15 mmol), [Reactants] and potassium phosphate (1546 mg, 7.28 mmol) in degassed DME (10 mL) at 20°C under nitrogen. The reaction was stirred at 100 °C for 24 hours. The reaction mixture was allowed to cool then filtered through celite, washing with ethyl acetate. The filtrate was evaporated under reduced pressure to give a brown residue. Not progressed any further.

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.
