Diphenylmethane (1) and dibenzyl (17) reacted with chlorosulphonic acid to give the corresponding p,p'-disulphonyl chlorides (2,18).However, attempted chlorosulfonations of α-chloro-, αα'-dichlorodiphenylmethane, stilbene and 1,4-diphenylbutadiene were unsuccessful.Diphenylacetic acid reacted with chlorosulfonic acid to give a mixture of 4,4'-dichlorosulfonylbenzophenone (40) and α-chlorodiphenylmethane-4,4'-disulfonyl chloride (39).Benzilic acid (41) afforded 9-chlorofluorene-2,7-disulfonyl chloride (42), which with amines gave 3 different products according to the reaction conditions.Fluorene (53) and the 9-carboxylic acid (43) have been treated with chlorosulfonic acid.The various sulfonyl chlorides were converted into 43 derivatives for biocidal evaluation.Mechanistic interpretations for the reactions is included.

A series of bis(1,4-benzoquinonemonoiminosulfonyl)derivatives of hydrocarbons were synthesized.During investigation of the electron affinity of these compounds by two methods (polarography and spectrophotometry of their charge-transfer complexes) consiste
