• further (see Supporting Information File 1, Figure S19). This comparison reveals that the Jackiephos supported gold accelerates the reaction more than (PhO)P(o-biphenyl)2 does, although this may be in part an anion effect [7]. The bis(trifluoromethyl)aryl substituent is expected to be more electron
