Alkynyl Fischer carbone complexes 1, which feature a pendant olefin group, undergo novel cascade processes triggered by [2+2], [3+2], and [4+2] cycloadditions. Competition between cyclopropanation and olefin metathesis is controlled by the substitution at

Treatment of (o-ethynyl)phenyl epoxides with TpRuPPh3(CH 3CN)2PF6 (10 mol %) in hot toluene (100 °C, 3-6 h) gave 2-naphthols or 1-alkylidene-2-indanones very selectively with isolated yields exceeding 72%, depen
