REACTION OF ARENEDIAZONIUM CHLORIDES AND SULFUR(IV) OXIDE WITH (2E,6E)-2,6-DIBENZYLIDENECYCLOHEXANONE AND (2E,2'E)-3,3'- BENZENE-1,4-DIYL-BIS(1-PHENYLPROP-2-EN-1-ONE)

It has been established that cuprous catalytic reaction of (2 E,6E)-2,6-dibenzylidenecyclohexanone or (2E,2'E)- 3,3' - benzene -1,4-diyl-bis(1-phenylprop-2-en- 1-one) with arenediazonium chloride and sulfur(IV) oxide leads to the formation of arylsulfonylation product by only one double bond. Substituted 2-benzyliden-6-((arylsul- fonyl)(phenyl)methyl)cyclohexanones and 3(4-(1-arylsul- fonyl-3-oxo-3- phenylpropyl)phenyl)-1- phenylprop-2-en- 1-ones) have been obtained.
