Paragraph 0046; 0047, (2019/12/25)
The invention discloses 1-methyl-3-(4-diacetoxyl iodobenzene methyl) imidazole chlorine salt as well as preparation and application thereof. The structure of the 1-methyl-3-(4-diacetoxyl iodobenzene methyl) imidazole chlorine salt is shown in the specification. The invention provides application of the 1-methyl-3-(4-diacetoxyl iodobenzene methyl) imidazole chlorine salt as a gold leaching agent. The application comprises the following steps: putting a sample with a noble metal into the 1-methyl-3-(4-diacetoxyl iodobenzene methyl) imidazole chlorine salt, and performing sufficient stirring so as to leach the noble metal. The 1-methyl-3-(4-diacetoxyl iodobenzene methyl) imidazole chlorine salt which is disclosed by the invention has good capabilities of oxidation and metal coordination, canbe used as the gold leaching agent, breaks through the defect that a toxic gold leaching agent is used in the conventional metallurgical industry, and has the advantages of being efficient, green andenvironment-friendly and sustainable.
Halogenation through Deoxygenation of Alcohols and Aldehydes

An efficient reagent system, Ph3P/XCH2CH2X (X = Cl, Br, or I), was very effective for the deoxygenative halogenation (including fluorination) of alcohols (including tertiary alcohols) and aldehydes. The easily available 1,2-dihaloethanes were used as key reagents and halogen sources. The use of (EtO)3P instead of Ph3P could also realize deoxy-halogenation, allowing for a convenient purification process, as the byproduct (EtO)3Pa?O could be removed by aqueous washing. The mild reaction conditions, wide substrate scope, and wide availability of 1,2-dihaloethanes make this protocol attractive for the synthesis of halogenated compounds.
