  Dienoic acids and pentadienyl alcohols are coupled in a decarboxylative and dehydrative manner at ambient temperature using Pd(0) catalysis to generate 1,3,6,8-tetraenes. Contrary to related decarboxylative coupling reactions, an anion-stabilizing group is not required adjacent to the carboxyl group. Of mechanistic importance, it appears that both the diene of the acid and the diene of the alcohol

  二烯酸和戊二烯基醇在环境温度下使用Pd（0）催化以脱羧和脱水方式偶联，生成1,3,6,8-四烯。与相关的脱羧偶联反应相反，在羧基附近不需要阴离子稳定基团。在机理上很重要，似乎该反应既需要酸的二烯，又需要醇的二烯。为了进一步理解该反应，研究了两个偶联配偶体每个唯一位置的取代，并提出了两种潜在的机理。
