By using N-acyliminium ion chemistry, several ω-propadienyllactams and a propadienyloxazolidine were prepared from N-acyliminium ion precursors and propargylsilanes. Treatment of these allene containing lactams and oxazolidinone with allyl halides or an a

A copper(I)-catalyzed semihydrogenation of internal alkynes has been developed. A variety of oxygen- and nitrogen-tethered N-heterocyclic carbene (NHC) complexes have been investigated, leading to a highly Z-selective transformation. The catalyst is generated from inexpensive copper(I) chloride in situ and allows catalytic semihydrogenation down to 10 bar H2.

Propargylsilanes RCCCH2Si(CH3)3 easily react with dialkyl alkylidenemalonates, in the presence of TiCl4, to lead to the only product corresponding to an 1,4-addition; the reaction takes place with propargylic rearrangement.
