Gold(i)-catalyzed cross-coupling reactions of aryldiazonium salts with organostannanes are described. This redox neutral strategy offers an efficient approach to diverse biaryls, vinyl arenes and arylacetylenes. Monitoring the reaction with NMR and ESI-MS provided strong evidence for the in situ formation of Ph3PAuIR (R = aryl, vinyl and alkynyl) species which is crucial for the activation of aryldiazonium salts.

Paragraph 0083-0084, (2020/11/19)
PROBLEM TO BE SOLVED: To provide a convenient production method of biphenyls which become the raw materials of medicines, pesticides and functional materials. SOLUTION: In the presence of a palladium catalyst and an alkali metal carboxylate, a 2,2'-bi(1,3,2-benzodioxaborole) derivative represented by general formula (1) (in formula, R1represents a hydrogen atom or a 1-4C alkyl group) and a benzene derivative A are made to react with each other, next, in the presence of an alkali metal phosphate or an alkali metal carbonate, a benzene derivative B is made to react therewith, and biphenyls represented by general formula (4) (in formula, each of R2and R3represents a hydrogen atom, a halogen atom, or the like, and each of n and m represents an integer of 1 to 4) are produced.

experimental part, p. 1700 - 1706 (2011/01/09)
Functionalized aryl and heteroaryl zinc reagents were prepared from aryl iodides and diethylzinc through t-Bu-P4 base-promoted iodine-zinc exchange reactions. The scope and limitations of this protocol, and several applications for the synthesis of oligoaryls and fused aromatics, are presented.
