摘要：

Treatment of LiC(TMS)(3)(THF)(2) with the nitrile 4-RC6H4CN in Et2O at ambient temperature yields the new lithium I-aza-allyl Li[N(TMS)C(C6H4R-4)C(TMS)(2)](THF) which readily eliminates LiN(TMS)(2) upon heating in refluxing benzene yielding the acetylene 4-RC6H4C=C(TMS) in quantitative (TMS = SiMe3; R = H, Br, OMe or Bu-t) or low (R = F) yield.
