The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.

Palladium-Catalyzed Asymmetric [3+2] Cycloaddition of Vinylethylene Carbonates with 2-Arylidene-1,3-Indandiones: Synthesis of Tetrahydrofuran-Fused Spirocyclic 1,3-Indandiones
An asymmetric [3+2] cycloaddition of 2-arylidene-1,3-indandiones with vinylethylene carbonates (VECs) had been achieved in the presence of Pd(2)dba(3)center dot CHCl(3)and axially chiral phosphoramidite ligand. The reaction of various substituted VECs and 2-arylidene-1,3-indandiones proceeded smoothly under mild conditions, giving the highly functionalized spirocyclic 1,3-indanedione derivatives in good to excellent yield with moderate diastereoselectivity and high enantioselectivity. The reaction on the gram scale had also been demonstrated.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 492-62-6, you can contact me at any time and look forward to more communication. Category: tetrahydrofurans.
