meso23dibromobutane

Meso-2,3-dibromobutane, commonly referred to as meso-2,3-dibromobutane, is an achiral stereoisomer of the compound 2,3-dibromobutane. Its molecular formula is C4H6Br2, and it is a vicinal dibromide derived from butane. The molecule contains two stereogenic centers at carbon atoms 2 and 3, each bearing a bromine and a methyl substituent. The meso form is characterized by an internal plane of symmetry, making it optically inactive despite having two potential stereocenters. The observed configuration is (2S,3R) (equivalently (2R,3S)).

In terms of synthesis and formation, meso-2,3-dibromobutane can arise when bromine adds anti across cis-2-butene, leading
