Table 2.
0.15 mmol scale, 1:2 = 1:2, 4:2 = 1:2, isolated yields.
Diastereomeric ratio (dr) and E/Z ratio was determined by 1H NMR analysis of crude reaction mixtures, using CH2Br2 as an internal standard.
Single diastereomer.
Xantphos Pd G3 (10 mol %) was used as a catalyst, and 1 equiv of PhMe2SiH was used. Xantphos Pd G3: [(4,5-bis(diphenylphosphino)-9,9-dimethylxanthene)-2-(2′-amino-1,1′-biphenyl)]palladium(II) methane-sulfonate.
Reaction was performed at 40 °C without light.
Styrene was not added.
