A 1,2‐bis(di‐tert‐butylphosphinomethyl)benzene‐modified palladium catalyst has been used to synthesize bifunctional monomers of different chain lengths from cardanol. Short‐chain derivatives of cardanol, such as (E)‐3‐(dodec‐8‐enyl)phenol; HOPhC12‐ene, (E)‐3‐(undec‐8‐enyl)phenol; HOPhC11‐ene, (E)‐3‐(dec‐8‐enyl)phenol; HOPhC10‐ene, and 3‐(non‐8‐enyl)phenol; HOPhC9‐ene, were synthesized by the metathesis
1,2-双(二叔丁基膦基甲基)苯改性的钯催化剂已用于从腰果酚合成不同链长的双官能单体。腰果酚的短链衍生物,例如(E)-3-(十二碳八烯基)苯酚;HOPhC 12烯,(E)-3-(十一碳8烯基)苯酚; HOPhC 11烯,(E)-3-(癸8烯基)苯酚; HOPhC 10烯和3-(非8烯基)苯酚; HOPhC 9烯是通过腰果酚与对称内部烯烃的复分解反应合成的。这些衍生物被甲氧基羰基化以产生具有不同链长的单体,例如16-16(3-羟基苯基)十六烷酸甲酯。最高法院15COOMe,-13-13(3-羟基苯基)十三烷酸甲酯; HOPhC 12 COOMe,12-12 (3-羟基苯基)十二酸甲酯; HOPhC 11 COOMe,11-11 (3-羟基苯基)十一酸甲酯; HOPhC 10 COOMe和10-(3-羟基苯基)癸酸甲酯; HOPhC 9 COOMe分别。MALDI-TOF-MS证实,合成的单体
