The reaction of [W(CCCSiMe3)(CO)2(Tp*)] (Tp* = hydrotris(dimethylpyrazolyl)borate) with MeLi generates the first example of an anionic allenylidene complex Li[W(CCCMeSiMe3)(CO)2(Tp*)] which reacts with electrophiles (H+, Me+) at the β-carbon to afford vinylcarbyne complexes and with bromine via oxidative C–C coupling at the β-carbon.

An efficient decarboxylative cycloaddition of 2,3-dioxopyrrolidines and ethynyl benzoxazinanones has been established by cooperative copper/amine catalysis. A copper– allenylidene complex and enolate intermediate, each catalytically generated from distinct substrates, underwent a cascade propargylation/hydroamination/aromatization process to construct a big library of cyclopenta[b]indole derivatives with good to excellent yields and excellent diastereoselectivity.
