The effect of calcium-based addition on the brominate flux during printed circuit board (PCB) pyrolysis was investigated. It was found that bromine (Br) can be effectively fixed in solid phase during PCB pyrolysis by adding calcium-based waste materials. Phenol and 4-ethylphenol are the major produc

An efficient route to natural occurring methyl 6-bromoindolyl-3-acetate 1c from methyl indolyl-3-acetate 3 was achieved in 3 steps and 68% overall yield. Thus, in order to regioselectively brominate 3 at the C6-position, introduction of electron withdrawing substituents at N1 and C8 was affected to

We described a synthesis method by first using chlorotrimethylsilane as the activator to brominate the Ni(II) complex of the beta-alanine Schiff's base [beta-AlaNi(II)PABA] 1 and developed it to prepare beta-amino acids 5. The procedure involves a Suzuki coupling reaction between boric acids and the
Brominated vegetable oil (BVO) is vegetable oil that has had atoms of the element bromine bonded to it. Brominated vegetable oil is used as an emulsifier in citrus-flavored soft drinks to help natural fat-soluble citrus flavors stay suspended in ...
