Synthesis of 1-methyl-2,2-diphenylethylene

Preparation of 1-methyl-2,2-diphenylethylene

Alternative Names: 1-Methyl-2,2-diphenylethylene; Prop-1-ene-1,1-diyldibenzene; 778-66-5; 1,1-Diphenyl-1-propene; 1,1-Diphenylpropene; (1-phenyl-1-propenyl)benzene;

The Grignard reagent is prepared from 6 g of dry magnesium, and 39 g of ethyl iodide (redistilled), 120 ml of anhydrous ether being used. 23 g of dry, finely divided benzophenone are added, the flask being cooled if the reaction becomes too vigorous. The mixture is then heated 6 hours on a water bath, treated with dilute acid, extracted with ether, the ether removed on a water bath, and the residue fractionated under reduced pressure, the fraction 169-170° C at 18 mmHg being separately collected and recrystallized from petroleum ether.
