摘要：
Alpha, beta, gamma! Amino substituents in alpha and beta positions allow the isolation of free carbenes, but even in the gamma position, their strong π-electron-donating properties permit the synthesis of allenylidene lithium adducts and silver complexes (see picture), which are ideal precursors for the preparation of various transition-metal-allenylidene complexes. © 2009 Wiley-VCH Verlag GmbH & Co.
