The borane ArB(OMe)2 (1) (Ar = 2, 4, 6-tri-tert-butylphenyl) was transformed into ArBH3*Li(tmeda) (2) by the action of LiAlH4 in Et2O.The product 2 can be hydrolysed to ArB(OH)H (3), but in strongly acidic media the hydrolysis involves the attack of a neighbouring methyl group to give the 1-hydroxy-1-boraindane derivative 4.Borane 3 can be dehydrogenated to 4 in the gas-phase at 600 deg C.The formation of ArBO (5) as an intermediate in this dehydrogenation has been proved by starting from ArB(OD)H (3') which gives the product 4 with an OH-group in the 1-position.
