The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.
Trimethyldiborane, (CH 3) 3 B 2 H 3 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: (CH 3 ) 2 BH 2 BH(CH 3 ) or dimethylborane and methylborane.
Trimethylborane was first described in 1862 by Edward Frankland, [6] who also mentioned its adduct with ammonia. [7] Due to its dangerous nature the compound was no longer studied until 1921, when Alfred Stock and Friedrich Zeidler took advantage of the reaction between boron trichloride gas and dimethylzinc.

Borane dimethylsulfide (BMS) is a chemical compound with the chemical formula BH 3 ·S(CH 3) 2.It is an adduct between borane molecule (BH 3) and dimethyl sulfide molecule (S(CH 3) 2).
Boron triiodide can be prepared by the reaction of boron with iodine at 209.5 °C or 409.1 °F. [citation needed] It can also be prepared by reacting hydroiodic acid with boron trichloride: 3HI + BCl 3 → BI 3 + 3HCl (reaction requires high temperature) Another method is by reacting lithium borohydride with iodine.
Tris(2,2,2-trifluoroethyl) borate can be prepared by reaction of trifluoroethanol with boron trichloride, borane dimethylsulfide, boron tribromide, or boric anhydride. The latter is more convenient for larger scale preparations due to its low cost and ease of handling. [4] CF 3 CH 2 OH + B 2 O 3 → B(OCH 2 CF 3) 3. The product is purified by ...
