presence of tetrafluoroboric acid gives the title monocarbocation compound, [4-(dimethylamino)phenyl]-3-guaiazulenylmethylium tetrafluoroborate (2), in 90% yield. The title investigations of compound 2 compared with those of two other monocarbocations stabilized by a 3-guaiazulenyl group (i.e. phenyl-3-guaiazulenylmethyl and [4-(isopropyl)phenyl]-3-guaiazulenylmethyl cations) are reported.
在四氟硼酸存在下,愈创木酚(1)与对-二甲基氨基苯甲醛在甲醇中的反应以90%的收率得到标题的单羰基化化合物,[4-(二甲氨基)苯基] -3-愈创木烯基甲基四氟硼酸酯(2)。报道了化合物2的标题研究与通过3-愈创木烯基(即,苯基-3-愈创木烯基甲基和[4-(异丙基)苯基] -3-愈创木烯基甲基阳离子)稳定的另外两个单碳原子化相比的标题研究。
