Cyclopropenes as Complex Ligands: Metal Induced Ring Opening and Carbonylation of a Bicyclopropenyl with Formation of a Tropone Derivative. The Crystal Structure of Tricarbonyl(4 - 7-η4-2,3,5,7-tetraphenyl-2,4,6-cycloheptatrien-1-one)-iron, (C6H2Ph4CO)Fe(CO)3

2,2',3,3'-Tetraphenylbi-2-cyclopropen-1-yl (1) reacts with Fe2(CO)9 at room temperature to form (4 - 7-η4-2,3,5,7-tetraphenyl-2,4,6-cycloheptatrien-1-one)Fe(CO)3 (3).This unexpected transformation of a bicyclopropenyl derivative into a tropone complex involves the opening of both cyclopropene rings, insertion of CO, and ring closure.Oxidation with Cer(IV) yields the uncomplexed tropone derivative.The crystal structure of the title compound 3 has been determined.
