Abstract Dicyclopropylacetylene has been brought into reaction under photolytic conditions with Fe (CO) 5 and under thermal conditions with Fe 2 (CO) 9 and with Fe 3 (CO) 12. It was possible to obtain primarily monoacetylene adducts or bis (acetylene) adducts by modification of the reaction conditions. In addition to products normally obtained from reactions of acetylenes with iron carbonyls, products derived from cyclopropane ring ...
