^aReaction conditions: 1 (2.0 mmol), aniline (1.0 mmol), WO₃/ZrO₂ (100 mg), n-octane (0.25 mL), 140 °C, 24 h.

^bIsolated yield.

^cSelectivity (mono : di) = ((isolated yield of N-allyl aniline)/[(isolated yield of N-allyl aniline) + (isolated yield of N,N-diallyl aniline)]) × 100 (%).

^dSmall amounts of the other compounds were contaminated.
