摘要：

The reaction of (BuM)-M-n (M = Li, Na) with [(R,R)]-bis(alpha -methylbenzyl)amine in the presence of pmdeta results in the formation of the chiral lithium amide complex (R,R)-{[Ph(Me)CH](2)NLi . pmdeta} and, remarkably, the sodium enamide, {[PhC(=CH2)NH]Na . pmdeta}(2); both compounds have been authenticated by single crystal X-ray diffraction.
