الإجراء التجريبي
Preformed lithium anthracenide was reacted with calcium iodide to prepare a soluble calcium species. This calcium species was added to chloromethylated polystyrene (DF=0.11) and stirred for 24 hours at room temperature. The corresponding calcium-substituted reagent was then reacted with chlorotrimethylsilane at room temperature to yield the silylated product; however, the yield was not optimized and was lower than the yield obtained from preformed lithium biphenylide (Table III, entry 4). Reaction of the calcium species with chloromethylated polystyrene at 0° C. for 6 hours resulted in a 100% loss of chlorine from the polymer. Subsequent reaction with benzaldehyde gave the corresponding secondary alcohol in 80% yield, compared to the 100% yield when calcium biphenylide was used (Table III, entry 6).
