title: Synthesis of allenylidene lithium and silver complexes, and subsequent transmetalation reactions.
abstract: Alpha, beta, gamma! Amino substituents in alpha and beta positions allow the isolation of free carbenes, but even in the gamma position, their strong pi-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.
