Abstract: Abstract Five-membered metallacycloallene compounds, 1-zirconacyclopenta-2,3-dienes 1, derived from but-1-en-3-ynes 2 and low-valent zirconocene, reacted with esters and isocyanates. Reactions of 1 with carboxylic esters such as ethyl acetate and methyl benzoate resulted in the formation… read more here.
