100% atom economic manner. Effects of nucleophilicity and sterical demands were revealed for monoalcohols, di‐ and polyols. Whilst yields, chemoselectivity and E/Z‐selectivity of the pelargonic acid derivatives were excellent with up to 99%, selectivity towards mono‐, di‐ and triesters could be controlled successfully. Finally, the reaction profile of the carboxytelomerisation glycerol was uncovered
钯催化的
1,3-丁二烯与醇的羧基端聚反应以原子经济和直接的方式产生不饱和C 9-
壬酸酯。尽管羧基端聚是当前关注的问题,但尚未充分研究适用的醇底物的局限性。在这里,我们提出的催化系统的转移包括
乙酸钯和三- Ñ
吡啶中的
叔丁基膦与20种醇的亲核性和空间要求差异很大,以100%原子经济的方式产生相应的酯。一元醇,二元醇和多元醇显示出亲核性和空间需求的影响。
壬酸衍
生物的收率,
化学选择性和E / Z选择性均极佳,最高可达99%,但对单酯,二酯和三酯的选择性仍可成功控制。最后,未发现羧基端粒化
甘油的反应曲线,产生了高达97%的工业相关不饱和C 9-短链脂肪。
