Contributions to the Chemistry of Boron, 182. - Attempted Preparation of Methyleneboranes: Studies of the Dehydrohalogenation of Sterically Crowded Amino-organylboron Halides

LiCMe3 reacts with tmpB(Hal)CHMe2 with substitution to give tmpB(CMe3)CHMe2 (tmp = 2,2,6,6-tetramethylpiperidino) but not by dehydrohalogenation.In the presence of Me2NCH2CH2NMe2 the aminoborane tmpB(NMe2)CHMe2 is also formed.Using Litmp in toluene the benzyl- and tolylboranes tmpB(R)CHMe2 are obtained.The (diphenylmethyl)boranes tmpB(Hal)CHPh2 react with Na(HBEt3) to produce tmpB(H)CHPh2, and substitution is also achieved with LiCMe3.While the 9-fluorenylboron fluoride tmpB(F)C13H9 is converted into tmpB(H)C13H9 by Na(HBEt3) the deep red tmpB(CMe3)C13H8Li (15) is formed in a 1:2 reaction with LiCMe3. 15 was characterized by its reaction products 13, 14 formed with HCl and CH3I, respectively.The formation of 15 is explained by a methyleneborane intermediate 2, resulting from dehydrofluorination of 11.
