Abstract

The reaction of sodium alkoxides [(RONa)-O-1, R-1 = CH3, CH3CH2, (CH3)(2)CH and CH3CH2CH2] with 2,4-diphenyl-1,3-diselenadiphosphetane-2,4-diselenide [PhP(Se)(mu-Se)](2) (Woollins' reagent, WR) gave the non-symmetric sodium phenyldiselenophosphonate salts 1a-1d, the latter were further treated with haloalkanes [(RX)-X-2, R-2 = alkyl and aryl; X = Br, Cl and I] or dihaloalkanes [Br-(CH2)(n)-Br, n = 1-3 and BrCH2C6H4CH2Br-p] to afford a series of new Se-alkyl O-alkylphenylphosphonodiselenoate esters 2a-2k and Se,Se'-dialkyl-O,O'-dialkyl bis(phenylphosphonodiselenoate) esters 3a-3j in good to excellent yields.
