Formula: C9H7BrS, Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. In a article, 1196-19-6, molcular formula is C9H7BrS, introducing its new discovery.
A simple, efficient, cheap, and broadly applicable system for the carboxylation of benzylic bromides with carbon monoxide and water is reported. Upon simple reaction with only 2.5 wt % of Pearlman’s catalyst and 10 mol % of tetrabutylammonium bromide in tetrahydrofuran at 110 C for 4 h, a range of benzylic bromides can be smoothly converted to the corresponding arylacetic acids in good to excellent yields after simple extraction and acid-base wash. The reaction was found to be broadly applicable, scalable, and could be successfully extended to the use of ex situ-generated carbon monoxide and applied to the synthesis of the nonsteroidal anti-inflammatory drug diclofenac.
