Borane adduct
An adduct (from the Latin adductus, "drawn toward" alternatively, a contraction of "addition product") is a product of a direct addition of two or more distinct molecules, resulting in a single reaction product containing all atoms of all components. The resultant is considered a distinct molecular species. Examples include the addition of sodium bisulfite to an aldehyde to give a sulfonate. It can j… WebBoranes (Dimethylsulfide Borane, Borane-Tetrahydrofuran Complex) Diborane (B 2 H 6), the simplest borane, is a useful reagent with many applications, ...
