fairly large excess of trimethylchlorosilane with 1 mole of acetamide under the same conditions produced in good yield u carboxamide which is bis-silylated at the amide group, viz. the hitherto unknown bis(trimethylsilyl)acetamide (I). This is a colorless liquid (b.p. 67.SoC/30 mm) and is very sens
## Abstract Armed monoaza‐15‐crown‐5 having a 4′,6′‐difluoro‐2′‐hydroxybenzyl group as an additional binding site (**2**) has been prepared by the Mannich reaction of __N__‐methoxymethylmonoaza‐15‐crown‐5 with 3,5‐difluorophenol. The reactive site on 3,5‐difluorophenol for the Mannich reaction was
