Abstract

1308140 Aromatic sulphones IMPERIAL CHEMICAL INDUSTRIES Ltd 10 July 1970 [31 July 1969 3 June 1970] 29910/70 and 26836/70 Heading C2C The invention comprises aromatic sulphones of formula wherein X is a fluorine or chlorine atom. These sulphones may be prepared by reacting a compound of formula A-SO 2 -Y where Y is a halogen atom, preferably chlorine, or a hydroxy group, with a compound of formula H-B under conditions in which YH is eliminated, to form a compound A-SO 2 -B where A and B are different and selected from groups. The examples describe the preparation of 4 - (4 - chlorophenylsulphonyl) - biphenyl and 4 - (4 - fluorophenylsulphonyl)- biphenyl. The following compounds which are not claimed are also prepared in the examples:
