    • A process is disclosed for the production of polyalkyl tetrahydronaphthalenes is disclosed wherein a cyclialkylation reaction between an olefinic compound of the general Formula ##STR1## wherein R.sup.4, R.sup.5 and R.sup.6 are independently defined and each represents a substituent which does not interfere substantially in Friedel-Crafts type reactions and R.sup.5 and R.sup.6 are other than H, and a substituted benzene compound is carried out in the presence of an alkyl halide, a Lewis acid and a phase transfer agent. The subject process produces the desired compounds in a surprisingly high yield, with a surprisingly high selectivity to the desired product, and at a relatively high rate of reaction, using better, more convenient, or less expensive process methodology than many processes known heretofore.
    • 公开了用于制备聚烷基四氢萘的方法,其中通式为“IMAGE”的烯烃化合物之间的环烷基化反应,其中R4,R5和R6独立地定义,并且各自表示在Friedel-Crafts中基本不干扰的取代基 类型反应,R5和R6不是H,取代的苯化合物在烷基卤,路易斯酸和相转移剂的存在下进行。 本发明方法以令人惊讶的高产率产生所需化合物,对所需产物具有出人意料的高选择性,并且以相对高的反应速率,使用比迄今为止已知的许多方法更好,更方便或更便宜的方法方法。

    • A process for the production of polyalkyl tetrahydronaphthalenes is disclosed wherein a cyclialkylation reaction between an olefinic compound of the general Formula ##STR1## wherein R.sup.5, R.sup.6 and R.sup.7 are independently defined and each is a substituent which does not interfere with a Friedel-Crafts type alkylation reaction, and a substituted benzene compound is carried out in the presence of an alkyl halide, a Lewis acid and a phase transfer agent. The subject process, which may be practiced in an unhalogenated hydrocarbon solvent, produces the desired compounds in a surprisingly high yield, with a surprisingly high selectivity to the desired product, and at a relatively high rate of reaction, using safer solvents and better, more convenient, or less expensive process methodology than many processes known heretofore.
    • 公开了一种制备聚四烷基四氢萘的方法,其中通式(IMAGE)的烯属化合物之间的环烷基化反应,其中R5,R6和R7独立地定义,并且各自是不干扰Friedel-Crafts型烷基化的取代基 反应,取代的苯化合物在烷基卤,路易斯酸和相转移剂的存在下进行。 可以在非卤化烃溶剂中实施的主题方法以令人惊讶的高产率产生所需化合物,对所需产物具有出人意料的高选择性,并且在相对高的反应速率下,使用更安全的溶剂和更好的,更多的 方便或较便宜的工艺方法。

    • A process is disclosed for the production of polyalkyl tetrahydronaphthalenes wherein a cyclialkylation reaction between an olefinic compound of the general formula ##STR1## wherein R.sup.4, R.sup.5, and R.sup.6 are substituents which do not interfere with a Friedel-Crafts-type reaction and R.sup.5 and R.sup.6 are other than H, and a substituted benzene compound is carried out in the presence of a hydride abstracting reagent, a Lewis acid, and, optionally, a phase transfer agent. In some embodiments, the subject process is specifically carried out in the absence of elemental iodine. The subject process produces the desired compounds in a surprisingly high yield, with a surprisingly high selectivity to the desired product, and at a relatively high rate of reaction, using better, more convenient or less expensive process methodology than many processes known heretofore.
