Non-acylated Quaternary Ammonium Salts from Aliphatic Amines 753 XIII did not readily add bromine. The methyl alcoholic filtrate of this experiment yielded 18.5% of IV when diluted with water, melting point and mixed melting point with a sample of this compound described in another experiment, 57°. This product also turned pink upon exposure to light.Acknowledgment.-We wish to express our appreciation to Mrs. M. S. Sherman for carrying out the recorded microanalyses. Summary The molecular rearrangement of fluorylidene dimethyl sulfide to fluorene-1 -dimethyl sulfide was effected in an alkaline medium. By graded oxidation the rearrangement product was converted into fluorene-1 -dimethyl sulfone, fluorenone-1-dimethyl sulfone and fluorenone-1-carboxylic acid. The above-named acid and its ethyl ester were characterized by comparison with authentic specimens. The -SCH3 group of fluorene-1 -dimethy 1 sulfide was substituted by -OCH3, -Br, -OH and -H. Fluorene-1methyl bromide in an alcoholic solution of sodium methylate yielded sym.-difluorene-1,1 '-ethylene and fluorene-1 -dimethyl oxide.
