  oxides and carbon dioxide into bio‐based cyclic organic carbonates catalyzed by Al(aminotriphenolate) complexes is reported. Both acyclic as well as cyclic terpene oxides were used as coupling partners, showing distinct reactivity/selectivity behavior. Whereas cyclic terpene oxides showed excellent chemoselectivity towards the organic carbonate product, acyclic substrates exhibited poorer selectivities

  据报道，高取代度的萜烯氧化物和二氧化碳难以结合到铝（氨基三酚盐）配合物催化的生物基环状有机碳酸酯中。无环和环状萜烯氧化物均用作偶联伴侣，表现出不同的反应性/选择性行为。环状萜烯氧化物对有机碳酸酯产物表现出优异的化学选择性，而无环底物由于伴随的环氧化物重排反应和不希望的低聚/聚醚副产物的形成而显示出较差的选择性。考虑到这些偶联反应的挑战性，目标生物碳酸盐的分离产率是合理的，在大多数情况下为50-60％。

  Constant-current electrolysis of geranyl acetate (2) in CH3CN-H2O afforded eight oxidation products (3-10) which were presumed to be formed through initial oxidation of the double bond at C6-C7. Based on the results of electrolysis of 2 in CH3CN-H218O, we have found that the oxygen atom(s) in the products (3-10) is(are) derived from water used as the reaction medium.

  在CH3CN-H2O中对乙酸香荆芥进行恒电流电解得到八种氧化产物（3-10），这些产物据信是通过对C6-C7双键的初始氧化形成的。基于在CH3CN-H2O中对2的电解结果，我们发现产物（3-10）中的氧原子来自于作为反应介质的水。

  2,3-Epoxygeraniol undergoes dissimilar rearrangements in contact with liquid superacids at low temperature or on solid superacids at room temperature due to different location of the arising cationic center depending on the superacid character. 2,3-Epoxynerol, 6,7-epoxycitronellol, and 6,7-geranyl acetate on ZrO2SO42 afford the corresponding ketones via epoxy ring opening followed by 1,2-hydride shift. With 6,7-geranyl acetate 7-oxanobornane formed as a minor product. The mode of generation of the cationic center (either the olefin protonation or the epoxy ring opening) affects the rearrangement direction at similar conditions.
