The reaction of long‐chain acyl thioesters, viz . lauric acid dodecyl thioester, 1,8‐di‐ S ‐palmitoyl octanedithiol, and tristearoyl α‐monothioglycerol, with trimethylsulfonium hydroxide in the presence of methanol leads to simultaneous derivatization of acyl moieties and S ‐alkyl moieties of acyl thioesters to the corresponding fatty acid methyl esters and methyl alkylsulfides, respectively. These derivatized products were analyzed by gas chromatographic technique.
