Procedure

2.50 ml (14.15 mmol) of 1,1-diphenylethylene were added at 25° C. to a suspension of 1.78 g (5.58 mmol) of dibenzylbarium in 70 ml of ethylbenzene and 10 ml of tetrahydrofuran (THF). Stirring for 14 hours resulted in a deep red solution. The solution was filtered off from small amounts of insoluble constituents and then evaporated to dryness. Solvent-free bis(1,1,3-triphenylpropyl)barium was firstly obtained as a very viscous, red-violet oil and, after prolonged drying, as a tough solid. The conversion was virtually quantitative.
