Table 2. Oxidative Heck Reactions with Acrolein (4a) or Methyl Vinyl Ketone (4b) and Different Boronic Acids^a.

^aReaction conditions: closed vessel charged with olefin (1.0 mmol), arylboronic acid (2.0 mmol), p-bzq (1.0 mmol), Pd(OAc)₂ (0.02 mmol), dmphen (0.024 mmol), and acetonitrile (7.5 mL) stirred at room temperature for 24–48 h.

^bIsolated yield with purity ≥95% (GC–MS). Yields were calculated according to 100% acrolein.

^cReaction conditions: sealed microwave vessel charged with olefin (8.58 mmol), arylboronic acid (0.613 mmol), p-bzq (0.333 mmol), Pd(OAc)₂ (0.0062 mmol), dmphen (0.0077 mmol), and acetonitrile (2 mL) with microwave heating at 100 °C for 30 min.

^dDMF as a solvent instead of acetonitrile.
