Triphenylphosphane (TPP) has been utilized as a novel and efficient catalyst for the Knoevenagelcondensation of aldehydes with acidic methylene compounds such as ethyl cyanoacetate and malononitrile to afford substituted olefins. The reaction proceeds smoothly under mild and solvent-free conditions and the products are obtained in excellent yields with an E-geometry. This method is applicable for

1,4‐Diazabicyclo[2.2.2]octane was used as an efficient catalyst in the Knoevenagelcondensation reaction of various kinds of aromatic/aliphatic/heterocyclic/αβ‐unsaturated aldehydes and ketones with active methylene compounds. This is a convenient and rapid method for Knoevenagelcondensation, which affords the corresponding substituted electrophilic alkenes in excellent yields. The reaction condition

radiations. The β-cyanoepoxides were isolated in good to excellent yields in a short reaction time. A convenient approach for the synthesis of β-cyanoepoxides is illustrated by iodine(III)-catalyzed epoxidation of electron-deficient β-cyanostyrenes, wherein the active catalytic iodine(III) species was generated in situ. The epoxidation of β-cyanostyrenes was performed using 10 mol% PhI as precatalyst in the
