    Bromobenzenes may be carboxylated into carboxylic acids using carbon monoxide.The reaction takes place in a two-phase mixture of p-xylene and water as solvent, in the presence of catalytic PdCl

  5. 4-Bromobenzaldehyde - Wikipedia

    en.wikipedia.org/wiki/4-bromobenzaldehyde

    4-Bromobenzaldehyde may be prepared in the laboratory in two steps by oxidation 4-bromotoluene. [4] In the first step, two bromine atoms are added to the methyl group of 4-bromotoluene by free radical bromination to form 4-bromobenzal bromide.

  6. Precursor cell - Wikipedia

    en.wikipedia.org/wiki/Precursor_cell

    In cell biology, precursor cells—also called blast cells—are partially differentiated, or intermediate, and are sometimes referred to as progenitor cells. A precursor cell is a stem cell with the capacity to differentiate into only one cell type, meaning they are unipotent stem cells. In embryology, precursor cells are a group of cells that ...
