aReaction conditions: aryl halide (0.057 mmol), phenylboronic acid (0.087 mmol), Na2CO3 (0.17 mmol), Pd catalyst (0.57 μmol, 1.0 mol%).
bYields are based on 1H NMR analysis of the crude products.
cFor Pd(PPh3)2Cl2 catalyst.
dFor Pd2(dba)3.
eFor Pd/C (5%).
fAfter exposure of the catalyst to air for 2.5 h.
g5 repeats with a standard deviation for both PdNP@3a and Pd/C (5%).
