Contributions to the Chemistry of Boron, 2031 Reactions of Some Non-Metallic Elements with 9-Fluorenylidene(2,2,6,6-tetramethylpiperidino)borane9-Fluorenylidene(2,2,6,6-tetramethylpiperidino)borane (1) is hydrogenated catalytically at its boron-carbon double bond producing 9-fluorenyl(2,2,6,6-tetramethylpiperidino)borane (2). Similarly, chlorine, bromine, and iodine add to this double bond, but only the bromine adduct 6a has been fully characterized. 1 is oxygen-sensitive. The oxidation product found is the 1,2-oxaboretane derivative 7, which is prepared independently by a [2 + 2] cycloaddition reaction from 1 and 9-fluorenone. Sulfur reacts with 1 to yield a trithiaborolane derivative, while P4 does not attach 1.
