The reaction of 3,3-dihexylcyclopropene 1 with carbon and amine pronucleophiles 2 in the presence of palladium catalysts proceeded smoothly to give the corresponding hydrocarbonation products 3, allylated nucleophiles, in good to high yields. For example, in the presence of catalytic amounts of Pd(PPh(3))(4) and dppf, the reaction of 3,3-dihexylcyclopropene with ethyl 2-cyanopropionate and ethyl 2-cyanophenylacetate
在钯催化剂的存在下,3,3-二己基环丙烯1与碳和胺原核亲核体2的反应顺利进行,从而以高至高收率得到了相应的烃化产物3,烯丙基化的亲核体。例如,在催化量的Pd(PPh(3))(4)和dppf存在下,3,3-二己基环丙烯与2-氰基丙酸乙酯和2-氰基苯基乙酸乙酯的反应生成了2-氰基-2-甲基乙酯-4-十一碳酸酯和2-氰基-2-苯基-4-十一碳烯酸乙酯的产率分别为82%和86%。
