Reactions of aryl halide vapor and calcium metal vapor were found to give the corresponding arylcalcium halides, ArCaX (X = F, Cl, and Br).Phenylcalcium halide, PhCaX (X = F and Cl), reacted with trimethylchlorosilane to give phenyltrimethylsilane.The reactions of phenylcalcium halides with acetone and benzaldehyde readily gave good yields of 1-methyl-1-phenylethanol and diphenylmethanol, respectively.Phenylcalcium halides reacted slowly with acetonitrile to afford acetophenone in poor yields.With ethyl acetate, phenylcalcium halides gave a mixture of 1,1-diphenylethanol and acetophenone.
