ALIPHATIC CHEMISTRY OF FLUORENE: PART VIII. BENZYL 9-FLUORENYL SULPHOXIDE AND SOME 9-FLUORENYL SULPHIDES

Allyl 9-fluorenyl sulphide, benzyl 9-fluorenyl sulphide, and di-9-fluorenyl sulphide are stable to boiling ethereal phenyl lithium, in marked contrast to the corresponding ethers. Benzyl 9-fluorenyl sulphoxide has been prepared and shown to be more weakly acidic than 9-fluorenyl sulphones.
