title:
- Carbonylation catalysis of aryl halides through active-site engineering
description:
- 'Catalyst characterization (PXRD, DRIFT, CO chemisorption, XPS, STEM) and catalytic testing data for
  Pd3P/SiO2 (a phosphorus-modified palladium phosphide catalyst, internal code ARNE01) compared against
  an unmodified Pd/SiO2 reference (ARNE02), for Pd-catalyzed carbonylation reactions of aryl iodides.
  31 batch reactor runs span three reaction types: alkoxycarbonylation (27 runs; mainly iodobenzene +
  ethanol -> ethyl benzoate, exploring reaction time, base, temperature, and substrate/nucleophile scope),
  phenoxycarbonylation (1 run, phenol nucleophile), and aminocarbonylation (3 runs, aniline nucleophile,
  100-140 C). PXRD additionally covers two further Pd3P/SiO2 loading variants (1 wt% and 10 wt% Pd), and
  STEM additionally covers a recycled/spent Pd3P/SiO2 sample recovered after catalytic testing; STEM method
  details are documented but no STEM image/data files are included in the deposited dataset.'
