Treatment of cis- or trans-ocimene with disodium tetrachloropalladate in methanol gives the π-allylpalladium(II) complex of geranyl methyl ether. In acetone solution, cis-ocimene is inverted to trans-ocimene, cyclised to limonene, and dimerised to a palladium(II)-complex of a C20-terpene dimer. Under similar conditions in methanol, myrcene is cyclised to bischloro-[1,α,β-trihapto-3-(1-methoxy-1-m
在甲醇中用四氯钯酸二钠处理顺式或反式-西庚烯,得到香叶基甲基醚的π-烯丙基钯(II)配合物。在丙酮溶液中,顺式-西甲烯被转化为反式-西甲烯,环化为柠檬烯,并二聚为C 20-萜烯二聚体的钯(II)-络合物。在甲醇中类似的条件下,月桂烯环化成双氯-[1,α,β-三七-3-(1-甲氧基-1-甲基乙基)-1-乙烯基环戊烷]钯-(II)},但在丙酮溶液中给出C 20的钯(II)络合物-二聚体。二聚体似乎是从头对头的C 10 –C 10二萜衍生而来的。
