CATALYTIC SYNTHESIS OF α-CYANO-α,β-UNSATURATED SULPHONES IN THE PRESENCE OF ORGANOTELLURIUM OXIDE

摘要

Using bis(p-methoxyphenyl)telluroxide(BMPTO)as the catalyst,phenylsulphonyl acetonitrile condensed easily with aromatic aldehydes atroom temperature to give -cyano- ,β-unsaturated sulphones in high yields.
