Other reactions. Blum et a/.15 report that the organometallic complex causes decarbonylation of carbonyl compounds and desulfonation of aromatic sulfonyl chlorides. They noted also that 20-g. samples of ethylbenzene, fluorene, and ace-naphthene on being heated with 100 mg. of rhodium complex for 5 hrs. at 130° are oxidized to the extent of 10-60% to acetophenone, fluorenone, and acenaphthenone. 

Cremlyn et aV examined the reaction of fluorene 39 with excess chlorosulfonic acid (six or twelve equivalents) or less reagent (three equivalents) in thionyl chloride. In each case, the product appeared to be a 1 1 mixture of the 2-sulfonyl chloride and the 2,7-disulfonyl chloride. The latter compoimd was obtained as the major product when fluorene-9-carboxylic acid was treated with a large excess of chlorosulfonic acid (twelve equivalents) in boiling chloroform (2 hours). ...
