presence of 10 mol% of Ni(acac)2, Ph2Zn reacts with 1,3-butadiene and aldehydes at room temperature to give 1-alkyl and 1-aryl substituted (E)-5-phenyl-3-penten-1-ols (3) in good yields. Under similar conditions, the three components of Ph3BZnEt2, isoprene, and aldehydes combine with each other to furnish 1-alkyl and 1-aryl substituted (E)-3-methyl-5-phenyl-3-penten-1-ols (5) in good yields.
在10摩尔%的Ni(acac)2存在下,Ph 2 Zn在室温下与1,3-丁二烯和醛反应,生成1-烷基和1-芳基取代的(E)-5-苯基-3-戊烯-1-醇(3),收率高。在相似的条件下,Ph 3 BZnEt 2的三种成分,异戊二烯和醛相互结合,生成1-烷基和1-芳基取代的(E)-3-甲基-5-苯基-3-戊烯-1-醇(5)丰产。
