2.7 g (110 mmol) of magnesium turnings were added to a solution of 2 g (11 mmol) of anthracene in 100 ml of THF, and a few drops of 1,2-dibromoethane were added. After the mixture had been stirred at room temperature for about 2 hours, the bright orange precipitate of magnesium anthracene had formed. A solution of 19 g (100 mmol) of 4-chlorobenzaldehyde dimethyl acetal in 100 ml of THF was added to the refluxing suspension over the course of 1 hour. After the mixture had refluxed for 4 hours, the yield of Mg 4-chlorobenzaldehyde dimethyl acetal according to GC analysis (determined as benzaldehyde after hydrolysis using dilute HCl) was 90%.
