反応手順
2-Isopropoxy-5-nonyl benzophenone was prepared as follows. To 25 g of 2-hydroxy-5-nonyl benzophenone in 100 mL CH2Cl2 was added 20 g NaOH in 100 mL water, followed by the addition of 48 g isopropyl bromide and 2.5 g tetra-n-butyl-ammonium bromide. The entire mixture was stirred vigorously at 40° C. for 3 days. The reaction mixture was worked up as described for the preparation of 2-methoxy-5-nonyl benzophenone (Example II) to give 16 g of yellow oil (57% yield), identified as the desired product.
