A general method for the preparation of α-phenylselanyl enones is described. Phosphorus ylides react with these α-phenylselanyl enones in a 1,4-addition, leading to cyclopropanes and/or dihydrofurans, depending on the substitution pattern. This unusual reactivity is due to the phenylselanyl moiety, hindering the carbonyl of the enone and making it less prone to 1,2-additions or promoting conjugate addition by electronic effects.

Indium(I) iodide efficiently promotes the chemio-, regio-, and stereoselective hydroselenation of 2-alkyn-1-ol derivatives with diphenyl diselenide to produce the Markovnikov adducts with stereochemistry corresponding to an anti addition of the selenol co
