, p. 3093 - 3098 (2020)
A transition-metal-free synthesis of spiro compounds from 9H-fluoren-9-ols mediated by hypervalent iodine is reported. In this reaction, an unprecedented β-carbon elimination of tertiary alkoxyliodine(III) to form new diaryliodonium salts is proposed. The

Paragraph 0023-0026, (2021/01/20)
The invention provides a synthetic method of chiral and achiral 2, 2 '-dihalogenated biaryl compounds (III), which comprises the following steps: by using diaryl cyclic iodonium salt and cheap halogensalt as raw materials, carrying out ring-opening reaction in one step under the catalysis of a copper salt to generate a 2, 2'-dihalogenated biaryl product; the method has the advantages of abundantraw material sources, low cost, simple operation and high yield, and the synthesized product has the advantages of diversified and novel structure and wide applicability;.
