  The invention relates to a process for the synthesis of diacids or diesters of general formula ROOC—(CH 2 ) x —COOR, in which n is an integer between 5 and 14, R is either H or an alkyl radical of 1 to 4 carbon atoms, from natural long-chain monounsaturated fatty acids or esters including at least 10 adjacent carbon atoms per molecule of the general formula CH 3 —(CH 2 ) n —CHR 1 —CH 2 —CH═CH—(CH 2 ) p —COOR, in which R is H or an alkyl radical with 1 to 4 carbon atoms, R 1 is either H or OH, and n and p, which are equal or different and are indices between 2 and 11. The method comprises: during a first step, converting the natural fatty acid or ester by pyrolysis or by ethenolysis, into a ω-monounsaturated fatty acid or ester of the general formula CH 2 ═CH—(CH 2 ) m —COOR, in which m is equal to p or p+1, depending on the nature of the processed fatty acid/ester and the conversion used; during a second step, submitting the product thus obtained to a metathesis or homometathesis reaction for obtaining a compound of the general formula ROOC—(CH 2 ) m —CH═CH—(CH 2 ) m —COOR, or cross-metathesis with a compound of formula R 2 OOC—(CH 2 ) r —CH═CH—R 3 , in which R 2 is either H or an alkyl radical front with 1 to 4 carbon atoms, r is either 0 or 1 or 2 and R 3 is H, CH 3 or COOR 2 , thus defining a cyclic or molecule or not, in order to obtain an unsaturated compound of the general formula ROOC—(CH 2 ) m —CH═CH—(CH 2 ) r —COOR 2 , and during a third step, converting the unsaturated compound into a saturated compound by hydrogenation of the double bond.
