Triphenylmethylcalcium chloride has been used in metalation reactions to prepare new organocalcium compounds. Metalation of indene leads to the isolable complexes (C9H7)2CaL2 (L = tetrahydrofuran or L2 = 1,2-dimethoxyethane) and sublimation of these complexes gives diindenylcalcium. (C9H7)2Ca. Similar metalation of cyclopentadiene occurs. Fluorene and phenylacetylene are metalated in tetrahydrofuran to give (C13H9)CaCl(THF)2 or (C6H5C2)CaCl-xTHF, respectively. IR and 1H NMR spectroscopic studies and other properties of the new products are discussed. © 1974.
