Reaction Steps
As a comparison when other alkylating catalysts were used, the maximum yield was about 16% at reflux temperature 83° C. At 25° C. GC showed at most only a trace amount of product. Catalysts used included BF3 /CH3OH, BF3 /H2O, BF3 -Et2O, triethyl-aluminum, CF3CO2H, AlCl3, H2SO4 (no solvent) and TiCl4. Only the BF3 and BF3 /CH3OH catalyzed reactions provided any measurable amount of product under the reaction conditions illustrated below.
