Nakagawa and coworkers reported a chiral ytterbium catalyst 34 which was prepared from l,l -(2,2 -bisacylamino)binaphthalene and Yb(OTf)3 in the presence of diisopro-pylethylamine by a method similar to that used for Kobayashi s chiral ytterbium reagent [52] (Scheme 1.65, Table 1.66). The amine also plays an important role in this reaction, because racemic cycloadducts were obtained without the tert-amine. Reduc-...

There are many electrophiles which not only terminate living polymer chains but also produce end-group substitution. For example, macromolecules with hydroxyl, carboxyl, thiol, or chlorine termini can be prepared by reacting living polymers with such compounds as epoxides, aldehydes, ketones, carbon dioxide, anhydrides, cyclic sulfides, disulfides, or chlorine (15-23). However, primary and secondary amino-substituted polymers are not available by terminations with 1° or 2° amines because living polymers react with such functionalities (1.). Yet, tert-amines can be introduced to chain ends by use of -N-N-di-methylamino-benzaldehyde as the terminating agent (24). 

Other telechelics of interest are amine-ended polymers. tert-Amine terminated polymers have been prepared by use of the tert-amine functional initiator,...
