- Abstract:
- The formal addition of propane to nonactivated double bonds can be
achieved with isopropyl chloroformate (2) in the presence of Et3Al2Cl3. Thus,
a 1:1 mixture of 10-isopropyloctadecanoic acid (3) and the 9-regioisomer is
formed from oleic acid (1). The reaction may also be carried out with
1-alkenes by the addition of triethylsilane as a hydride donor.
