Purecha Group: We specialize in Fine 4-Bromo benzaldehyde Chemicals, Specialty Chemicals and Bromination Compounds. Our company's future is one of leadership in a 4-Bromo benzaldehyd and widening spectrum of Specialty market.
4-Bromo Benzaldehyde will react with alkenes in aqueous solvents to give bromohydrins and preferred conditions are the portionwise addition of NBS
to a solution of the alkene in 50% aqueous DMSO, DME, THF. Formation of a bromonium ion and immediate attack by water gives strong Markovnikov
addition and anti stereochemical selectivities.
