  The reaction mechanisms of cyclic 1,3-diketones with trialkyl orthoformates and trimethyl orthoacetate in the absence of activators were theoretically and experimentally studied. The reactions proceed via C-C-coupling of the ionized forms of the reactants giving dialkyl acetals, which further transform into vinyl ethers. The reactions of the latter with ortho esters afford aldehydes (ketones). Related

  从理论上和实验上研究了环状 1,3-二酮与原甲酸三烷基酯和原乙酸三甲酯在没有活化剂的情况下的反应机理。反应通过反应物的电离形式的 CC 偶联进行，得到二烷基缩醛，其进一步转化为乙烯基醚。后者与原酸酯的反应提供醛（酮）。相关的 2-乙酰环戊酮在氩气下与原乙酸三甲酯反应形成甲基烯醇醚的混合物，而在空气氧存在下形成戊二酸二甲酯。

  A non-photosensitive silver dimer compound comprises two different silver salts, provided that when the two different silver salts comprise straight-chain, saturated hydrocarbon groups as the silver coordinating ligands, those ligands differ by at least 6 carbon atoms. Many of these silver dimer compounds can be represented by the following Structure I: wherein each E is independently oxygen, sulfur, nitrogen, selenium, or tellurium, R and R' are different alkyl groups, aryl groups, aromatic heterocyclic groups, or halo atoms, provided that when E is oxygen, R and R' are both straight-chain, saturated hydrocarbon groups, those hydrocarbon groups differ from each other by at least 6 carbon atoms. These silver dimer compounds are useful in thermally-developable imaging materials including thermographic and photothermographic materials.
