Abstract: The present invention relates to a novel method for producing diarylpyridine derivatives, and the object of the present invention is to provide a novel, industrially useful method. The present inventors developed a novel method for synthesizing pyridine rings without using palladium, a strong base, or a high-temperature reaction. In particular, they successfully developed a method that can be used to synthesize iminium salts as intermediates, synthesize cyano compounds from these iminium salts, and cyclize the cyano compounds into pyridines under very mild reaction conditions.

Abstract: A heat-generating sheet (1) for IH cooking heaters composed of a laminate sheet including a conductive layer (3) and a dielectric layer (5). The laminate sheet has a bottom section (10) and a peripheral side wall section (13) and can be folded into the shape of a container A having the conductive layer on the inner side; a plurality of first cutlines (7) are formed at intervals in the peripheral direction in the conductive layer corresponding to the peripheral side wall section of the container A formed by folding and reduce or cut off the induction of an eddy current produced by the induction heating of an IH cooking heater, and a reinforcing ring (20) made of a dielectric material is fixed to the dielectric layer corresponding to the periphery of the bottom section of the container A and keeps the shape of the container A.
