A facile and efficient AgF-mediated Hofmann-type reaction of N-tosyl cyclicimides with silicate esters was developed. The N-tosyl cyclicimides undergo a Hofmann-type rearrangement/alkoxylation reaction in which the silicate ester acted as the alkoxy source. This reaction proceeds under simple and mild conditions to generate a series of anthranilic acid-derived carbamates in moderate to good yields
