Abstract
The reaction of p-tert-butylcalix[4]arene with either tris(dimethylami no)methylsilane or trichloromethylsilane yields 3, a novel silyl triet her derivative with a pendent phenolic group, which should serve as a valuable precursor to substituted calix[4]arenes. We demonstrate its u tility in the high-yield synthesis of the mono-O-methylated p-tert-but ylcalix[4]arene 6 via O-methyl silyl compound 5.
