The reaction of an alkyl halide with silver nitrite yields nitroalkanes and alkyl nitrites

The claim is a standard, well-established chemical reaction taught in organic chemistry (often referred to as the Kornblum nucleophilic aliphatic substitution or general synthesis of nitroalkanes using silver nitrite). Although most retrieved papers are off-topic reviews on unrelated metal-catalyzed or organic transformations, paper [3] directly discusses the reaction of alkyl halides with silver nitrite. As a universally recognized principle of chemistry, this qualifies as common knowledge, but paper [3] provides direct supporting evidence for the reaction.
