Le triméthyldiborane est un composé organo … Le triméthyldiborane est un composé organoboré de formule chimique CH3HBH2B(CH3)2. À température ambiante, il est à l'équilibre avec le méthyldiborane H2BH2BHCH3, le 1,1-diméthylborane H2BH2B(CH3)2, le 1,2-diméthyldiborane CH3HBH2BHCH3, le tétraméthyldiborane (CH3)2BH2B(CH3)2 et le triméthylborane B(CH3)3, de sorte qu'il est difficile de disposer de triméthyldiborane pur. Il se présente comme liquide pyrophorique dont le point de fusion est de −122,9 °C et le point d'ébullition de 45,5 °C.,9 °C et le point d'ébullition de 45,5 °C.
, Trimethyldiborane, (CH3)3B2H3 is a molecul … Trimethyldiborane, (CH3)3B2H3 is a molecule containing boron carbon and hydrogen. It is an alkylborane, consisting of three methyl group substituted for a hydrogen in diborane. It can be considered a mixed dimer: (CH3)2BH2BH(CH3) or dimethylborane and methylborane. called 1,2-dimethyldiborane. Other combinations of methylation occur on diborane, including monomethyldiborane, 1,2-dimethyldiborane, tetramethyldiborane, 1,1-dimethylborane and trimethylborane. At room temperature the substance is at equilibrium between these forms, so it is difficult to keep it pure.The methylboranes were first prepared by H. I. Schlesinger and A. O. Walker in the 1930s.Schlesinger and A. O. Walker in the 1930s.
