Murakami, Masahiro published the artcileMolybdenum-Catalyzed Ring-Closing Metathesis of Allenynes, Product Details of C10H16O2, the publication is Organic Letters (2005), 7(18), 3953-3956, database is CAplus and MEDLINE.
A ring-closing metathesis reaction of allenynes I [X = 4-MeC6H4SO2N; PhCH2N, (MeO2C)2C, (EtO2C)2C; R1 = H, Me; R2 = Me, Me2CH; R3 = H, Me, Et, Ph; R2R3 = (CH2)5] occurred at room temperature in the presence of a molybdenum alkylidene complex to give ring-closed vinylallenes II. The vinylallene skeletons were constructed by a metathesis-type reaction between the alkyne moiety and the proximal carbon-carbon double bond of the allene moiety.
