2，2‘-亚甲基双(4，6-二叔丁基苯氧基)可作为双齿Lewis酸同时与羰基配位，从而加速Diels-Alder反应。通过与相应的单齿锂试剂的比较，强调了双齿锂试剂对羰基的双重活化能力。(C)1998爱思唯尔科学有限公司。保留所有权利。
Dilithium 2,2'-methylenebis(4,6-di-tert-butylphenoxide) can be successfully utilized as a bidentate Lewis acid for simultaneous coordination to carbonyl groups, thereby accelerating the Diels-Alder reactions. The double activation ability of the bidentate lithium reagent toward carbonyls is emphasized in comparison with the corresponding monodentate lithium reagent. (C) 1998 Elsevier Science Ltd.
