COA of Formula: C7H5BrO The article mentions the following:
A green and highly effective solvent-free protocol has been reported for the synthesis of N,N’-alkylidene bisamides RC(O)NHCH(Ar)NHC(O)R (R = Me, Ph; Ar = Ph, 3-O2NC6H4, 4-BrC6H4, etc.) via the reaction of arylaldehydes (1 equivalent) with primary amides (2 equivalent) in the presence of saccharin-N-sulfonic acid (SaSA) as a solid-acid catalyst. The mentioned compounds have been obtained in high yields and short reaction times. In the part of experimental materials, we found many familiar compounds, such as o-Bromobenzaldehyde(cas: 6630-33-7COA of Formula: C7H5BrO)
o-Bromobenzaldehyde(cas: 6630-33-7) is used in L-threonine aldolase-catalyzed enantio/diastereoselective aldol reactions.COA of Formula: C7H5BrOIt is a key starting material in the total synthesis of an anticancer agent, (-)-taxol.
