A total of ten C18 fatty esters containing an azido group and another chemical function (ethylenic, bromo, epoxy, hydroxy, methoxy, acetoxy or vinyl) were synthesised from methyl ricinoleate. Methyl di-and triazidooctadecanoate were also derived from methyl oleate and ricinolcate, respectively. The
