1,1-Dimethylallene reacts with phenolic substrates in the presence of catalytic amounts of platinum(II) complexes. A regiospecific C-alkenylation takes place, affording o-isopentenylphenols and 2,2-dimethylchromans. Possible reaction mechanisms are also discussed.
在催化量的铂(II)配合物的存在下,1,1-二甲基丙烯与酚类底物反应。发生区域特异性的C-烯基化,得到邻-异戊烯基苯酚和2,2-二甲基苯并二氢吡喃。还讨论了可能的反应机理。
