A collection of phosphine oxide allenes has been prepared. Their coordination to gold(I) has been studied giving new coordination complexes when a pendant pyridine moiety was present. Alternatively, their gold(I)-catalyzed cycloisomerization has proven to
Low temperature organocopper-mediated two-component cross coupling/cycloisomerization approach toward N-fused heterocycles

(Chemical Equation Presented) Organocopper reagents smoothly react with heterocyclic propargyl mesylates at low temperature to produce N-fused heterocycles. The copper reagent plays a "double duty" in this novel cascade transformation, which proceeds via an SN2′ substitution followed by a subsequent cycloisomerization step.
Lewis base-catalyzed alkynylation of carbonyl compounds with trimethylsilylacetylenes
Kitazawa, Takayuki,Minowa, Tomofumi,Mukaiyama, Teruaki
, p. 1002 - 1003 (2007/10/03)
Alkynylation of carbonyl compounds with trimethylsilylacetylenes in the presence of a catalytic amount of Lewis bases such as acetate or phenoxide anion is described. The alkynylation proceeded under mild conditions and afforded the corresponding propargyl alcohols in good to excellent yields. Copyright
