Abstract:
Unsaturated fatty acids C8H17CH=CH(CH2)nCO2H] (n=7, 11) acids are cleanly dihydroxylated by hydrogen peroxide in the presence of catalytic amounts of H2WO4. Under molecular oxygen, in the presence of catalytic amounts of N-hydroxyphthalimide and Co(acac)3, the diols resulting from erucic (n=11) and oleic (n=7) acid undergo C–C cleavage.
