with primary and secondary allylic alcohols. The reactions, carried out in aqueous ethanol in the presence of palladium(II) acetate as precatalyst and sodium hydrogen carbonate as base, gave the arylation products with good overall conversion. In all cases, the major products were the β-arylated carbonyl derivatives. The o-benzene-disulfonimide was recovered in high yield from all the reactions, and it
芳烃重氮邻苯二磺酰亚胺与伯和仲烯丙醇反应。在醋酸钯 (II) 作为预催化剂和碳酸氢钠作为碱的存在下,在含水乙醇中进行的反应得到了具有良好总转化率的芳基化产物。在所有情况下,主要产物都是 β-芳基化羰基衍生物。从所有反应中以高收率回收邻苯二磺酰亚胺,并将其循环用于制备其他盐。

The reaction of cerium(IV) as cericammoniumnitrate (CAN) with a variety of allylic and tertiary benzylic ethers and esters has been examined in different alcohols and acetic acid under catalytic and mild conditions. Experiments have been conducted to elucidate the scope of this ether-to-ether, ether-to-acetate and acetate-to-ether transformations.
