Abstract
The mechanism of the reaction of dicarbonyl(η5-cyclopentadienyl)phenyliron, 1, with diphenylacetylene to give 2,3-diphenyl-[1,H]-inden-1-one has been investigated using a partially deuterated 1. The mechanistic pathway of the reaction is discussed in terms of the labelling of the indenones obtained. The reaction of phenylacetylene with 1 gives a mixture of products including 2,4,6-triphenyl-4′-methylbenzophenone and C-4,C-6a-dihydro-4-(4′-methylphenyl)-2-phenylpentalene(1-r-3aH)one. Keywords: indenones, acetylenes, iron, carbonyl.Keywords
