array of α,α-dialkyl-α-(phenylselanyl)acetates has been synthesized very efficiently from readily available a,a-dialkyl-a-cyanoacetates, by use of lithium naphthalenide induced reductive α-selenenylation as a key operation. Moreover, the selanyl esters thus generated in situ could be converted further, in a one-pot treatment with hydrogen peroxide and acetic acid, into the corresponding α,β-unsaturated
