  Described are methods of making organic compounds by metathesis chemistry. The methods of the invention are particularly useful for making industrially-important organic compounds beginning with starting compositions derived from renewable feedstocks, such as natural oils. The methods make use of a cross-metathesis step with an olefin compound to produce functionalized alkene intermediates having a pre-determined double bond position. Once isolated, the functionalized alkene intermediate can be self-metathesized or cross-metathesized (e.g., with a second functionalized alkene) to produce the desired organic compound or a precursor thereto. The method may be used to make bifunctional organic compounds, such as diacids, diesters, dicarboxylate salts, acid/esters, acid/amines, acid/alcohols, acid/aldehydes, acid/ketones, acid/halides, acid/nitriles, ester/amines, ester/alcohols, ester/aldehydes, ester/ketones, ester/halides, ester/nitriles, and the like.

  本发明描述了通过偏合成化学制造有机化合物的方法。本发明的方法特别适用于从可再生原料（如天然油）中提取的起始组合物开始制造工业上重要的有机化合物。这些方法利用与烯烃化合物的交叉甲基化步骤，生成具有预定双键位置的官能化烯中间体。一旦分离出来，官能化烯中间体可进行自甲基化或交叉甲基化（例如与第二种官能化烯），以生产所需的有机化合物或其前体。该方法可用于制造双官能团有机化合物，如二酸、二酯、二羧酸盐、酸/酯、酸/胺、酸/醇、酸/醛、酸/酮、酸/卤化物、酸/腈、酯/胺、酯/醇、酯/醛、酯/酮、酯/卤化物、酯/腈等。
